Force = ma

We know, the unit that the S.I. unit of mass is Kg.

We also know that a = (v - u)/t.

We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.

We know that the S.I. unit of d(displacement) is m.

So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.

So, the S.I. unit of a is m/s×s or m/s²

So, the unit of force is

(unit of m) × (unit of a)

= kg × (m/s²)

= kg.m/s²

=

[tex]kg \: m \: {s}^{ - 2} [/tex]

Or more simply,

F = ma

=> F = m{(v-u)/t}

Putting units,

Newton = kg[{(m/s) - (m/s)}/s]

=> Newton = kg{(m/s)/s}

=> Newton = kg(m/s²)

=> Newton = kg.m/s²

=> Newton = kg.m.(s^-2)

The importance of water properties on plants and animals.

The importance of water in plants is that it helps plants to make their own food, because water plays a very important role in Photosynthesis, and as well it helps them to grow.

The important of water in animals is that it is main need for animals to survive as well as humans. Without water even a single organism won't exist in this Earth.

The human body is made up of more than three-fourths of water, and all animals and plants require water to thrive.

Water is used by all living things to transport nutrients throughout the body and remove waste. Among its many crucial functions, water aids in the digestion of food and the preservation of organisms' heat.

The term "universal solvent" refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.

Water's function as a solvent aids cells in the transfer and utilization of molecules like oxygen or nutrients on a biological level.

Therefore, to do all the cellular processes by plants and animals there is need of water.

Answer:

Tibia and fibula. Tibia (medial bone)

Explanation:

The tibia is the medial bone of the lower leg (it is the second-largest bone next to the femur), whereas the fibula is the lateral bone of the lower leg. The tibia functions to transmit the majority of the force in the lower leg. The tibia articulates at the proximal end with the femur and fibula; where this bone (tibia) articulates at the distal end with the fibula and the talus bone of the ankle. The tibia and fibula are connected via an interosseous membrane, which is a thin sheet of connective tissue that spans the space between two bones.

From the given information:

The study observes the genes present in mice for eye color and tail length. Since both genes are linked, it implies that they exist in the same chromosomes.

Black eyes is dominant over apricot eyes

Let Black eye be B and apricot eyes be b

Long tail is dominant over short tail

Let long tail be L and short tail be l

If double heterozygote(homoozygous-recessive) engage in the testcross

Then:

From the result given:

The parental combinations are:

Apricot eyes, Longtail  (bL / bl) =  33

Black eyes, Short tails (Bl / bl) = 30

The recombinant genes are:

Black eyes, Long tails (BL / bl) =  17

Apricot eyes, Short tails (bl / bl) = 20

The recombination frequency relates to the distance between the two genes which can be computed as:

= (20+17)/100

= 37%

Thus; the heterozygous parent is in trans arrangement.

Answer:

Crossing over

Explanation:

Prokaryotic cells are cells that do not possess a membrane bound nucleus to house their genetic material e.g bacteria while eukaryotic cells possess a membrane bound nucleus that houses their genetic material e.g plants.

One important characteristics of prokaryotic cells is that they do not undergo any form of sexual reproduction, hence, cannot undergo MEIOSIS, which only occurs in sexual reproducing organisms. Prokaryotes reproduce asexually by binary fission.

Crossing over is a unique process that only occurs during meiosis. Since prokaryotic cells do not undergo meiosis, this means that crossing over is the difference between prokaryotic cells and eukaryotic cells in this question.

The compound action potential increases in amplitude with an increase in stimulation voltage is due to recruitment of small diameter axons followed by large diameter axons in the nerve.

The part of a nerve cell (neuron) that transports nerve impulses away from the cell body is known as an axon. A neuron has one axon that connects it to other neurons, muscle cells, and gland cells.

Compound action potential measurement capabilities are built into cochlear implants and are used as objective measures during device setup and programming. Because the stimulus recruits many fibers simultaneously and synchronously, the response is called a compound action potential because it is the sum of the many potentials recruited.

The amplitude of the reaction is increased via summation and synchronous production, making detection possible. A variety of diagnostic methods include recording the electrical activity of peripheral nerve neurons. A second deflection will emerge in the displayed waveform when we gradually increase the stimulus voltage using the control knob on the stimulator.

Explanation:

Answer:

Sexual reproduction is able to generate genetic variation in offspring by 1-independent assortment and 2-recombination during meiosis, and 3-random fertilization.

Explanation:

Sexual reproduction is a type of reproduction that increases the amount of genetic variation in offspring by three main mechanisms: independent assortment of homologous chromosome pairs and recombination during meiosis, and random union of gametes during fertilization. First, sexual reproduction is associated with the independent assortment of chromosomes during meiosis, i.e., the orientation of homologous chromosome pairs is a random process that is different for every cell that undergoes meiosis. In consequence, chromosomes assort randomly into gametes, thereby the segregation of alleles of a gene pair is independent of the segregation of another set of alleles of a different gene (as stated in the law of independent assortment). Second, sexual reproduction generates genetic variation by recombination, which is the exchange of genetic material between non-sister chromatids during meiosis I (prophase I). This genetic process (recombination) is able to generate new alleles in offspring. Third, sexual reproduction also involves the random union of two haploids (n) gametes during fertilization, which results in the formation of a diploid (2n) zygote that develops into a new individual. In humans, the sperm cell has 8 million possible (2²³) chromosome combinations, which fertilizes an ovum cell that also has approximately 8 million chromosome combinations, thereby producing a tremendous genetic variation in offspring (around 64 trillion possible zygote combinations).

Answer:

- When a neuron is stimulated and sodium channels open, the process of depolarization has begun.  

- Structures of the nervous system surrounding, but not part of the central nervous system are part of the peripheral nervous system

- Two consecutive neurons communicate at a synapse, where they physically come together.  

- Endorphins are a group of natural chemicals that reduce the perception of pain.  

- Supporting cells of the nervous system are collectively called neuroglia

- When potassium channels have been open long enough to go below resting membrane potential, hyperpolarization has occurred.

Explanation:

Neurons undergo depolarization in response to diverse stimuli (e.g., heat, light, electrical, chemical, etc). The depolarization occurs when sodium (Na+) ions pass through specific channels  (i.e., open voltage-gated Na+ channels) into a neuron, which causes an increase in the positivity of membrane potential. On the other hand, hyperpolarization occurs when potassium (K+) channels remain open and Na+ channels reset, thereby producing an increase in negativity of membrane potential. The peripheral nervous system (PNS) is composed of the cranial nerves, spinal nerves, peripheral nerves, and neuromuscular junctions, which connect the Central nervous system (CNS) to the organs, limbs, and skin. Endorphins (e.g., serotonin) are polypeptides secreted by the pituitary gland and CNS to relieve stress and pain. Neuroglia refers to a class of neural cells that have ectodermal (e.g., astroglia, peripheral glial cells) or mesodermal (e.g., microglia) origins. Neuroglia cells are involved in diverse roles, including, among others, the formation of the blood-brain barrier, homeostatic support, provision of nutrients for neurons, structural support to nerve cells, etc.

answer:

P( first child having PKU )  0.25 ≤ x ≤ 0.5

Explanation:

The pedigree father has PKU ( pp ) ( From the top right )

pedigree mother = PP

The possible resultant progeny = Pp  

Resultant progeny marries non-carrier  ( Pp x PP ) = PP , PP, pP, pP

Hence B is either  ; PP ( non carrier ) or Pp ( carrier )

From left

one of the Resultant progeny = pp ( affected ). this simply means pedigree parents where both carriers or sufferers i.e. Pp or pp

Hence A is either ; Pp or pp

The probability of their first child having PKU

= PP x Pp = PP, Pp, PP, Pp ( probability = 0 in this case )

= Pp x Pp = PP, Pp, pP, pp ( probability = 1/4 * 100 = 25% )

= Pp x pp = Pp, Pp, pp, pp ( probability = 2/4 * 100 = 50% )

P( first child having PKU )  0.25 ≤ x ≤ 0.5

Answer:

Females of reproductive age lose iron through menstrual blood

Explanation:

Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.

Answer:

D

Explanation:

Should be correct I guess.

Answer:

1. Acetylcholine:  

- Muscarinic  

- Nicotinic  

- Associated with mushroom poison  

- Only receptor found in parasympathetic synapses  

- Associated with tobacco  

2. Norepinephrine:  

- alpha-Adrenergic  

- beta-Adrenergic

- Utilizes calcium ions as a second messenger

Explanation:

Acetylcholine (ACh) is a neurotransmitter that acts in both the central and peripheral nervous systems. Cholinergic receptors are receptors that bind to ACh. Muscarinic receptors are G protein-coupled receptors involved in the parasympathetic nervous system, which play roles in a variety of physiological responses (e.g., ACh binds to muscarinic receptors in the pathophysiology of asthma, leading to an increased mucus secretion). Nicotinic receptors bind to nicotine, while muscarinic receptors bind to muscarin (muscarine is a well-known neurotoxic alkaloid found in certain mushrooms). Nicotine receptors are also called cholinergic receptors since they also respond to ACh.  On the other hand, norepinephrine (NE) binds to alpha-adrenergic and beta-adrenergic receptors in different tissues. Both alpha-adrenergic and beta-adrenergic receptors are G-protein coupled receptors. Alpha-adrenergic receptors are involved in the regulation of blood pressure and generating a sympathetic 'fight and flight response'; whereas beta-adrenergic receptors modulate sympathetic responses in the cardiovascular, metabolic, and central nervous systems (NE activates the beta1-receptor). NE can induce Ca2+ release, which is a second messenger that controls a wide variety of cellular processes.

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular locus. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given locus (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).
