In general, do organisms that have more traits in common also share more genes?

Answers

Answer:

In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.

Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form. Liver phosphorylase a concentration decreases when glucose enters the blood. As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. Liver phosphorylase a is regulated by AMP, adenosine monophosphate. When PP1 is bound to phosphorylase a, both PP1 and phosphorylase a are active.

Answers

Answer:

Liver phosphorylase a concentration decreases when glucose enters the blood.

The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form

As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form

Explanation:

Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.  

Which of these is a difference between DNA and RNA?

DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.

Answers

Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

when is the best time to harvest crops?why?​

Answers

[tex] \huge \bold \blue{★Question★}[/tex]

When is the best time to harvest crops? why?

[tex] \huge \bold \blue{★Answer★}[/tex]

Correct timing of harvest is crucial to crop loss prevention. Grain losses may occur caused by rats, birds, lodging, insects, and shattering. Timely harvesting ensures good grain quality and high market value.

Harvesting too early will result in a higher percentage of unfilled or immature grains, which will lower the yield and cause higher grain breakage during milling. Harvesting too late will lead to excessive losses and increased breakage in rice. Harvest time also affects the germination potential of rice seed.

[tex] \huge \mathsf \orange{MORE \: ABOUT :)}[/tex]

There are different ways to determine the correct harvest time:

Moisture content

Grain moisture content ideally is between 20−25% (wet basis). Grains should be firm but not brittle when squeezed between the teeth.

Ripe grains per panicle

The crop should be cut when 80−85% of the grains are straw (i.e., yellow-colored).

Number of days after sowing

Generally, the ideal harvest time lies between 130 and 136 days after sowing for late, 113 and 125 for medium, and 110 days for early-maturing varieties.

Number of days after heading

For dry season harvesting, an optimum time is 28 to 35 days after heading. In wet season harvest, optimum time is 32 to 38 days after heading.

Other considerations

Harvesting also needs to be timed so that threshing can be done as soon as possible after cutting to avoid rewetting and to reduce grain breakage.

If the crop has a lot of surface moisture, (e.g. from previous rainfall or early in the morning), it is advisable to wait until the surface moisture dries off.

Are Parakeets good starter pets? why or why not

Answers

Answer:

NO! They require a ton of attention, a large cage, and experience with birds. Parakeets are often marked as starter pets, but no, they are not.

First, they need a 3 feet long cage with 5+ toys that need to be changed each month. And they need natural perches, not the cheap wooden dowels, they will get feet problems. Most people don't do this, having a bored pet.

Second, parakeets will chew anything given/available to them, and a lot of things can be toxic to them, which can lead to the death of your pet.

Third, parakeets are messy and noisy. They poop a LOT and love to toss seeds around their cage. They also need millet and a calcium chew, which are also messy.

They also will want a friend, they are flock animals in the wild so 3-4 birds is a good number, but getting more birds means getting a large cage. The pet store will tell you it's fine, but it is not. ALWAYS SEEK HELP FROM A BIRD BREEDER.

Lastly, they need a bird proofed room to fly around in. No matter how large your cage is, they still need some out-of cage time.

Try a dove or pigeon instead, they are listen the #1 easiest and cheapest to care for pet bird.

Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?

Answers

Answer:

For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

b. Adaptation
c. Biodiversity
d. Homeostasis​

Answers

Answer:

B adaption

Explanation:

The scenario in which the Pandas evolve longer wrists to better eat bamboo over a long period will increase the possibility of artificial selection. The correct option is A.

What is artificial selection?

Artificial selection, also renowned as "selective breeding," is the practice of selecting for positive traits in agricultural products or animals rather than allowing the species to change and evolve naturally, as in natural selection.

The process by which organisms can choose individual lifeforms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve.

Adaptation entails dealing with both the physiological abiotic environment such as light, dark, temperature, etc. but in addition to the intricate biotic environment.

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase their possibility of survival. This is an example of artificial selection.

Thus, the correct option is A.

The largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.

What do you mean by Endocrine Gland?

An endocrine gland may be defined as a type of gland which consists of several organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. These hormones control many important functions in the body, including growth and development, metabolism, and reproduction.

The pancreas is the largest endocrine gland that significantly makes three hormones namely, Insulin, Glucagon, and Somatostatin. These hormones are actively involved in the regulation of metabolism by numerous mechanisms.

For example, insulin lowers the level of sugar in the blood, while glucagon increases the level of sugar by transforming its storage form.

Therefore, the largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.

They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp.

This is because eliminating them would cause a trophies cascade. The sea otter’s prey would increase, and the prey of that prey would decrease. Thus, otters are a “keystone” species.

What do you mean by osmosis?

Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.

Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Osmosis is one of the most important ways that plants and animals achieve homeostasis.

The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. Therefore, the water flows into the roots. The guard cells of the plants are also affected by osmosis.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube

Answers

Answer:

Diffusion and active transport.

Explanation:

Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.
