* Explain about monohybrid and diyhybrib cross with the help of punnet square​

Answers

Answer 1
In a monohybrid cross, such as the one in Figure below, the Punnett square shows every possible combination when combining one maternal (mother) allele with one paternal (father) allele. In this example, both organisms are heterozygous for flower color Bb (purple). Both plants produce gametes that contain both the B and b alleles. The probability of any single offspring showing the dominant trait is 3:1, or 75%. To develop a Punnett square, possible combinations of alleles in a gamete are placed on the top and left side of a square. For a monohybrid cross (Table below), individual alleles are used, whereas for a dihybrid cross (Table below), pairs of alleles are used. A Punnett square for a monohybrid cross is divided into four squares, whereas a Punnett square for a dihybrid cross is divided into 16 squares. How many boxes would a Punnett square need if three traits were examined? The squares are filled in with the possible combinations of alleles formed when gametes combine, such as in a zygote.

which of the following would differ if you compared the same reaction taking place with and without an enzyme

a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction

Answers

Answer:

The correct answer is - option C.

Explanation:

Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.

Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.

Thus, the correct answer is - option C.

Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?

Answers

Answer:

By changing the transition state and pH of the medium

Explanation:

Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.

The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.

Answers

Answer:

The correct answer is - option E.

Explanation:

The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.

On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin  and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.

Thus, the correct answer is option E.

The pygmy shrew is the smallest mammal in North America. However, when comparing the amount of
food eaten to its body weight, the pygmy shrew eats more food than any other mammal. It will
consume two to three times its own body weight in food daily. One explanation is that the pygmy
shrew uses energy at a high rate. In fact, its heart beats over one thousand times per minute.
What is the best explanation for what happens to the food's mass and energy when it is consumed by
the pygmy shrew?
A. The mass is mostly excreted as waste. The
energy is burned up and destroyed by the
pygmy shrew's high rate of cellular respiration.
B. The mass is all used for creating new mass in
growth. The energy is stored, used in cellular
respiration, or lost to the environment as heat.
C. The mass is used for growth, stored, or excreted
as waste. The energy is stored, used in cellular

Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).

How Pygmy shrew uses its food for energy?

The pygmy shrew has a large appetite which is a result of small body mass, rapid heat loss and high metabolic rate. It is kept in captivity which provides some idea of ​​the energy requirements of the species.

The pygmy shrew has such a high metabolism that it must eat at least every 30 minutes otherwise it will die. This can be explained by food mass and energy is that due to very high metabolism most of the food mass which is rapidly used up to form shrew, and a large proportion of the food is lost from the body surface because of its very small size.

The combination of these two factors are

1. A very high metabolism which is rapidly utilizes food material, and generates large amounts of heat in a very short period of time.

2. Very small size due to which high surface area to volume ratio leading to heat loss.

Thus, Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).

Why are G protein only found in Eukaryote cell ?

Answers

Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.

Answers

The correct answer is C. Its neighborhood is not clear.

Explanation:

One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.

In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?

Answers

Answer:

In mitosis, each centromere has a spindle attached on both side of centromere

Explanation:

In mitosis, each centromere has a spindle attached on both side of centromere because Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where replicates are linked together.

Spindle fibers are active in mitosis and also meiosis and they move throughout the cells and also direct chromosomes to move to where they need to move to.

Spindle fibers function in centromere in mitosis and meiosis by pulling homologous chromosomes apart after they might have been replicated to prepare for division.
