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?
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.

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.
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.

The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: *
A. pituitary gland
B. thyroid gland
C. pancreas
D. adrenal gland
Answer:
The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: thyroid gland.
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.

A consistent response in many organisms to changing environmental temperatures is the restructuring of cellular membranes.In some fish, phosphatidylethanolamine (PE) in the liver microsomal lipid membrane contains predominantly docosahexaenoic acid, 22:6 at C-2 of the glycerol-3-phosphate backbone and then either a saturated or monounsaturated fatty acyl group at C-1. Which of the following statements are False?
a. At 10 degrees Centigrade a lower percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
Ñ. At 30 degrees Centigrade a lower percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
e. The purpose of membrane restructuring with a change in temperature is to maintain fluidity of the membrane.
Answer:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Explanation:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Reason -
When temperature decreases, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases that also decreases the fluidity of the membrane and thereby make it stiff.
When temperature increases, the proportion of unsaturated fatty acids decreases and saturated fatty acids increases that makes the cell membrane more fluidic.
So, the temperature changes restructures the membrane with respect to fluidity of membrane.
Therefore,
At 10° Celsius, at C-1 of glycerol, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases.
At 30° Celsius, the proportion of unsaturated fatty acid decreases and saturated fatty acid increases.
For the voltage-gated sodium channel to allow sodium into the cell:_______.
a. the activation and inactivation gates must both be open
b. only the activation gate must be open
c. only the inactivation gate must be open
d. the inactivation gate must be closed shortly before the activation gate opens
e. the activation and inactivation gates must both be closed
Answer:
The correct option is - (a) the activation and inactivation gates must both be open.
Explanation:
Option (a) is correct because of the following reason -
The axonal membrane is at its natural resting potential until an action potential occurs, and [tex]Na^+[/tex] channels are deactivated and blocked on the extracellular side by their activation gates. The activation gates open in response to an electric current, allowing positively charged [tex]Na^+[/tex] ions to flow into the neuron through the channels. When enough [tex]Na^+[/tex] has penetrated the neuron and the membrane potential has reached a certain level, the [tex]Na^+[/tex] channels inactivate themselves by closing their inactivation gates at the height of the action potential. The inactivation gate can be thought of as a "plug" tethered to the intracellular alpha subunit's domains III and IV. When the inactivation gate is closed, the flow of [tex]Na^+[/tex] through the channel is stopped. As a result, both the activation and inactivation gates must be open to enable sodium ions to enter the cell.
Hence , the correct option is (a).

based on the information on the map where are the most stable ecosystems usually found?
The correct answer is C. Near the equator.
Explanation
The image shows a world map in which there is a horizontal black line in the middle that represents the equator line and some red areas. These areas are the most stable ecosystems in the world since due to their proximity to the equator the incidence of the sun's rays is more direct. Also, in these areas, there is no weather pattern defined by seasons, but climates are defined by altitude, that is, meters above sea level. Therefore, the correct answer is C. Near the equator.

if im wrong ill give you your points
Osmosis best describes how glucose is absorbed into intestinal cells.
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.
