Explanation:
describe the effects that enzymes can have on substrates
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
Explanation:
Hope this helps.
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process

Which of these organisms would most likely be found at the top of an energy pyramid?
a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).

Describe the path that energy takes, from solar energy reaching earths surface to energy used to power cell processes in animals
The path that energy takes, from solar energy reaching the earth's surface to energy used to power cell processes in animals - Animals eat the grass that captures the energy from the sun which gives the animal nutrients
The Sun is the primary source of energy for organisms and the ecosystems of which they are part.
Producers, such as plants and algae, get their energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.This process begins the flow of energy through almost all food webs.The energy present in these photosynthetic organisms store then transferred to various animals when they feed on these plants and algae and get their food and energy.Thus, the correct answer would be - Animals eat the grass that captures the energy from the sun which gives the animal nutrients

name the things which help in the preparation of carbohydrates in plants
Answer:
People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.

What might happen in this ecosystem if the fox was removed?
Answer:
The numbers of rat will increase & fox eaters will decrease in ecosystem
If the fox was removed from the ecosystem, the number of primary consumers i.e, herbivore may increase drastically that will cause heavy loss to vegetation.
What is the importance of foxes?Foxes being the most widely distributed canine on diverse habitats of earth. Regardless of significant member of secondary consumers, foxes are important indicators of food web stability and hospitable terrain wherever they live.
Red foxes help to hold control on rodent and rabbit populations, which causes heavy loss to vegetation if present in greater number.
Foxes also may assist in seed dispersal by eating fruits and their fur adhere seed to be carried where they navigate.
Thus, if the foxes are removed from the ecosystem, it will negatively impact the ecosystem by imbalancing the food web.

6. D. It breaks down glucose to form ATP.
7. D. All autotrophs are producers
8. D. All 4 statements are correct.
9. False
10. False
Explanation:
The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.
In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.

Number of chromosomes?
Sex of individual?
Normal? Yes or no.
If abnormal, what chromosome pair?
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
_____________________________________CHROMOSOMAL NUMBER 18:Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
_____________________________________TRISOMY 18:Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.
_____________________________________Best Regards!'Borz'There are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
What is the chromosomal abnormality?The chromosomal abnormality is caused by the mutation in the chromosome number and includes either the deletion of the chromosome or the addition of the chromosome in a homologous pair. The chromosomal abnormality has many negative consequences as well, some extra copies in the sex chromosome pair cause infertility, etc., while deletion causes life-threatening conditions.
Hence, there are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
