Aquatic animals have various structural modifications in their body to adapt to the aquatic habitats. Some of the adaptations of aquatic animals are:
Their body is streamlined and hence, they can swim easily.
They have gills as the respiratory organs.
They have fins as the locomotory organs, Various types of fins are present in fishes such as dorsal fins, pectoral fins, caudal fins etc.
The body is covered by appendages known as scales. They are meant for protection.
Some fishes have modified swim bladder with the help of which they can constantly float at a certain depth of water.

describe how the structure of the cuticle, palisade mesophyll, spongy mesophyll and guard cells are adapted for their functions
Answer:
cuticle
In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
adapted( function)
The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface. ... They can also reduce the rate of transpiration by blocking air flow across the leaf surface.
palisade mesophyll
Light absorption happens in the palisade mesophyll tissue of the leaf. Palisade cells are column shaped and packed with many chloroplasts . They are arranged closely together so that a lot of light energy can be absorbed.
adapted ( function)
The palisade mesophyll layer of the leaf is adapted to absorb light efficiently. The cells: are packed with many chloroplasts. are column-shaped and arranged closely together
spongy mesophyll
Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells. ... To enter the leaf, gases diffuse through small pores called stomata.
adapted (function)
Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water.When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them
Guard cell
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it.
Adapted (function)
Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. This helps to stop the plant from wilting
Assume that you are a genetic counselor and that a couple seeks genetic counseling from you. Both the man and the woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this couple will produce a child with a genetic syndrome as the result of crossing over within the pericentric inversion
Answer:
50%
Explanation:
An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?
The correct answer is A. Geological processes.
Explanation
Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.

Explanation:
1）Fishing boats have decreased the number of herring in the sea. Explain why that could affect the number of offspring puffins can raise.
2） Which animals have a bigger food supply now there are fewer herrings?
3） Global warming is expected to reduce the biomass of phytoplankton in the oceans. What effect will that have on the rest of the food web?
Explanation:
1) When the number of herrings decrease, the food available for the puffins decrease and therefore they will not be able to feed their offspring. This will cause the number of offspring to decrease.
2) Any other animal(s) which hunts and eats the same prey as a herring will now have a bigger food supply.
3) When the biomass of phytoplankton decrease, the next animal in the food web will not have any food and their numbers will decrease, decreasing the number of the animals next in the web, as they too lose their food. This will continue for the rest of the food web and the number of animals will decrease.
After photosynthesis, how will producers get their energy? Producers receive glucose from the intake of oxygen. Producers will release glucose into the atmosphere, feeding the ecosystem. Producers will create glucose, which is the primary source of food. Producers will receive glucose directly from any rainfall that occurs.
Answer:
After photosynthesis (Producers will create glucose, which is the primary source of food)
Explanation:
The biotic component of an ecosystem is made up of all living organisms in it. These organisms are divided into two main groups according to the way they feed:
--> Producers (autotrophs) and
--> Heterotrophs.
Producers are organisms that are able to use sunlight or chemical energy to manufacture their own food (glucose) from simple inorganic substances. This process is known as photosynthesis. Producers include all green plants, photosynthetic protists and some bacteria
Producers extract inorganic nutrients and chemical energy from their non-living environment, that is, from the abiotic component of the ecosystem. Since autotrophs are the only organisms that can produce food in an ecosystem, they are also known as PRIMARY FOOD PRODUCERS.
PRODUCERS use some of the food they produce for their activities and building their body tissues (growth). The rest is stored in various parts of the body.
Answer: Its C, Producers will create glucose, which is the primary source of food.

In a separate maddyase experiment using (Et)-10nM, the reaction velocity is measured as 3uMS. What is the substrate concentration used in the experiment
Answer: hello your question has some missing data attached below is the missing data
Applying the Michaelis-Menten Equation
An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.
answer :
substrate concentration [ x ] = 10⁻⁵ M
Explanation:
Given data:
[Et ] = 10 * 10⁻⁹ M ,
Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹
applying Michaelis-Menten Equation
= 3* 10⁻⁶ = [tex]\frac{600 *10*10^{-9} * (X) }{10^{-5} + (X) }[/tex] ,
= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )
hence the substrate concentration [ x ] = 10⁻⁵ M

Answer:
This question is incomplete, it is asking to fill in the missing gaps as follows:
The principle of dominance is a ______ inheritance pattern.
It’s states traits that are ______ mask the traits that are______
The answers to the missing gaps are: MENDELIAN, DOMINANT, RECESSIVE
Explanation:
Gregor Mendel proposed the principles that govern inheritance. These principles are called MENDELIAN inheritance pattern because they align with or follow the principles of Mendel. One of these principles by Mendel is the LAW OF DOMINANCE.
Mendel has previously stated that there are two alleles for each gene. Each contrasting allele encodes a different phenotype. However, the law of dominance states that one of these two alleles called DOMINANT allele has the ability to mask the phenotypic expression of the other allele called RECESSIVE allele. In other words, a dominant trait will mask the recessive trait.
For example, in a gene Tt, allele 'T' for tallness is dominant and hence, will mask the phenotypic expression of allele 't' for shortness. This means that the tall trait (dominant) will mask the short trait (recessive) as explained by Mendel's law of dominance.
