Answer:

Isn't it Galileo.

I think it is Galileo

Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!

Answer:

Environmental quality refers to the quality of the total environment, including both the natural and the built environment.

Natural Environment- Plants, animals, natural resources, etc.

Built Environment- Man-made structures and facilities.

Humans

Explanation:

The main cause of pollution is the burning of fuel, over-use of fertilizers and pesticides, carelessness, and the improper disposal of waste. And who does this? Not casper, not pennywise, not animals, but us humans. So we are the main reasons why pollution exist.

You can just write what causes pollution (the underlined), you dont need to write about who causes it.

Answer: Sensory Neurone and a synapse

[tex]\Huge\text{1) Sensory Neurons}\\\\\Huge\text{2) Synapse}[/tex]

Reflex action is a involuntary and instantaneous action in response to a stimulus acting over a reflex arc. Some reflex actions are inherited and innate while other are acquired through learning processes. These reflex actions are performed without the will of the animal & generally involve minimum number of neurons.

Many neurons work in group called reflex arc, There must be atleast two neurons in a reflex arc. A reflex arc is made possibly a shortest pathway so the body acts on an impulse before it reaches the brain, and usually it is coordinated by spinal cord and brain-stem.

The parts of reflex arc is given as,

The change in the body is detected by receptors which gives the information to the brain or spinal cord which is the control center via the sensory neuron. The control center decides the appropriate response and sends it to the effector via motor neuron which plays its role.

[tex]\Large\textbf{Synapse:}[/tex]

a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells or the muscle.

Complete question:

Snow leopards live in the high reaches of the Himalayas and have several adaptations to deal with living most of the time in snow. They have wide paws with hair between the toes to allow them to run on top of the snow crust. Assume that wide paws (W) and hair between the toes (T) are both dominant traits and are on the same chromosome. Suppose that two snow leopards, heterozygous for both traits, mate. Suppose further that in the female, the two dominant alleles are on the same chromosome of the homologous pair, while in the male, each chromosome of the pair has one dominant and one recessive allele.

1) What percentage of each of the following genotypes will be produced?

2) How many of the offspring (assume 4 cubs) will have narrow paws with hair between the toes?

constructive population pyramid (B)

Answer:

C) Stabilizing Population Pyramid

the population is stabilizing

Because the death rates are falling and life expectancy is longer, the population is stabilizing.

Answer:The germination process is commonly regulated by many abiotic factors, both individually and interactively, and these include light, temperature, pH, burial depth, soil salinity and moisture.

Answer:

Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells.

Answer:

Harvey

Explanation:

The study of specific characteristic and mechanism of animals or plants that makes it to exits living organisms is called physiology. Thus this could be plant, animals insects physiology.

In 1628 Harvey for published a book, titled An anatomical exercise on the motion of the heart and blood in living beings.  That was  the first time the word physiology was used.

He used the tam to  distinguish between natural and supernatural causes of things in the book.

The publication of this book formed the golden age of physiology in Nederland as early s 1628

Answer:

Explanation:

f(x) = 3x-15

f(0) = 3 (0) -15

3* 0 = 0

0-15 = -15

Answer:im guessing its the greenhouse effect

Explanation:The Earth's atmosphere is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). ... Due to increases in gases, like carbon dioxide, that trap heat being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance creating the greenhouse effect

Answer:

Tyr Ile Leu Ala Thr Thr

Explanation:

In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of  20 amino acids and these amino acids are coded by a pair of three bases.  

There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).

The given mutated DNA sequence will also code for some amino acid, that is as follows:

TAC - Tyr (Tyrosine)

ATC - Ile (Isoleucine)

TTG -  Leu (Leucine)

GCG - Ala (Alanine)

ACG - Thr (Threonine)

ACT - Thr (Threonine)

Thus, The mutated DNA sequence  TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.

Answer:

Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.

Explanation:

Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.

The cross can be represented by a Punnett Square:

Bb X Bb cross

alleles     B    b

B             BB Bb  

b             Bb bb

Where the result is:

Genotypes:  

Phenotypes:

In this case, the probability of having brown or red feathers is 3:1.

Answer:

A

Explanation:

Meiosis end in four daughter cells that are haploid and contain half the chromosomes as the parent cell and genetically different from the parent cell and from each other, so A would be the right answer.

A haploid set of chromosomes that are a recombination of the parents' chromosomes  best describes the genetic complement in each daughter cell at the conclusion of meiosis.

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.

Moreover, meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.

Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

The third answer down.

Answer:

C

Explanation:

hope this helps :)

Answer:

C. BbSs

Explanation:

The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.

This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.

So, the genotype must be C, BbSs

The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.

The parent's genotype will then be BbSs.

The genotype of both parents have to be heterozygous as a result of the

presence of its forms in the B and S traits. There is the presence of the

dominant (B,S) and recessive traits (bs).

The genotypes of the parent will however have both traits in them which

translates to the option C) BbSs being the most appropriate.
