Refer to Animation: Filtration, Reabsorption, Secretion. What drives the reabsorption that occurs in animal excretory systems

Answers

Answer 1

Answer:

Reabsorption,  Higher

Explanation:

What drives the reabsorption to take place in the executory system is the presence of slow diffusion of some substances and active transport for others. Filtration removes the water form the blood and other substances get dissolved into blood.

Write down the functions of
1.microtubules
2.tripletsof microtubules

Answers

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Hope it helps :)

Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

Which of the following is NOT a stage in the cell cycle?
A. Gap 1
B. Gap 2
C. Development
D. Mitosis

Answers

Answer:

C. Development

Explanation:

The cell cycle involves two major kinds of division; mitosis and meiosis. These divisions is each composed of stages/phases. Mitosis, for example, is divided into: interphase and mitotic (M) phase.

The interphase stage consists of Gap 1 (G1) phase, Synthesis (S) phase and Gap 2 (G2) phase while the mitotic phase consists of mitosis and cytokinesis etc. Hence, according to the question, development is not a stage of the cell cycle.

The "homunculus" constructed on the basis of somatosensory representations in the human primary somatosensory cortex

Answers

Answer:

The correct answer is -

a. has a grossly enlarged face and hands compared to torso and limbs

c. is distorted because of the disproportionate representation of certain body parts relative to others in the somatosensory cortex

Explanation:

" Homunculus" is a graphical representation of a small but fully grown man which the foetus is believed to develop whereas somatosensory homunculus is a neurological representation of the brain of humans that shows the motor and sensory functions of the body.

It has a large number of sensory nerves from the hand that take a large part of the brain. The face also has many nerve endings and are represented by large areas of the homunculus. A distorted look comes from this uneven representation of different body parts in the homunculus.

how are hydrogen bond similar to iconic bonds?

Answers

Explanation:

Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. ... This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.

Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges

Answers

Answer:

a)the outermost part of an animal cell that selectively allows things to pass through and come out.

b) the passing of water molecules from higher conc. to lower conc.

Answer:

(a) Semi-permeable membrane:

A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.

(b) Osmosis:

The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.

When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

How are ions transported around the plant

Answers

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Xylem moves water and so do mineral ions from the roots to the leaves where amino acids are. From there they move to the rest of the plant

Which of the following can be inferred from the genetic code?

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answers

Answer:

A. All organisms have a common biochemical evolutionary origin.

Explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

Answer:

How long the dog runs without stopping

Explanation:

The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.

In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.

Why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?
A. Mammal cells are larger and can produce greater volumes of protein.
B. Mammalian cells are not needed; bacterial cells can produce the same proteins as long as they have the gene that codes for it.
C. Mammal cells have more precise restriction enzymes.
D. Bacteria make proteins differently than mammals, and cannot make certain human proteins.

Answers

Answer:

C

Explanation:

As mammal cells have more precise restriction enzymes, it sometimes needed instead of bacteria. The correct option is C.

What is genetic engineering?

Genetic engineering also referred to as genetic modification is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

Because mammalian cells have more precise restriction enzymes, it is sometimes necessary to use them instead of bacteria.

Herbert Boyer and Stanley Cohen, biochemists, create genetic engineering in 1973 by implanting DNA from one bacteria into yet another.

There are three basic stepping stones to genetic engineering. These are:

Isolating DNA fragments from a donor organism.Inserting an isolated donor DNA fragment into a vector genome.Growing a recombinant vector in an appropriate host.

Thus, the correct option is C.
