Answer:
They are compounds made of the same two elements, but each contain different numbers of atoms. ... There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass. Why is this statement true? Hydrogen atoms have a lower mass than oxygen atoms.
Answer:
The statement is true because there is more of the actual atom hydrogen in living organisms, as oxygen is more abundant in the world, but not in every living organism.
Explanation:
For example, there is more hydrogen in living organisms added up, but there is more oxygen in the world. If you add them all up, the mass of oxygen would be more then hydrgen, but more hydrogen in actual living organisms.

d.
are ectothermic
Answer:
D - Are ectothermic; (took the test)
Explanation:
Reptiles are cold-blooded, scaly vertebrates.
Reptiles are the Chordata that belongs to the animal kingdom and are covered with the scaly body. All reptiles are ectothermic or cold-blooded. Thus, option d is correct.
What are the characteristics of reptiles?Reptiles are the vertebrates that have backbones and scaly bodies hence Chordates. The dry skin of the reptiles is covered by scales and bony plates. They have four legs and have intermediate properties between mammals and amphibians.
They breathe through the lungs, and almost all reptiles lay eggs and hence are oviparous. They have cold-blooded metabolisms and hence are ectothermic. They regulate and maintain the internal body temperature according to the external environment.
Therefore, all reptiles are ectothermic (cold-blooded).

Why would an enzyme that is effective with one reaction have no effect on another reaction?
Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.Answer:

Sex hormones, secreted in greater amounts in females than males, and
contributes to female sex characteristics *
Answer:
Your answers are probably estrogen and oxytocin.
The sex hormone that is secreted in greater amounts in female and contribute to female sex characteristics is estrogen.
Sex hormones are those hormones that are secreted by both male and female which are used for sexual development and reproduction.
Example of sex hormones include estrogen
This sex hormone is secreted both in female and in male but in greater amounts for females.
This is because males secrete more of the sex hormone, testosterone
The estrogen contributes to female sex characteristics through the following ways:
it contributes to the development of the reproductive system,Development of breast and public hairs. Estrogen contributes to cognitive health , bone health, the function of the cardiovascular system , and other essential bodily processes.
Therefore The sex hormone that is secreted in greater amounts in female and contribute to female sex characteristics is estrogen.

Predators Contribute to a Stable Ecosystem
In nature, energy flows in only one direction. Transfer of energy must occur in an ecosystem
because all life needs energy to live, and only certain organisms can change solar energy into
chemical energy. Producers are caten by consumers that are, in turn, caten by other consumers,
Stable ecosystems must contain predators to help control the populations of consumers. Since
ecosystems contain many predators, exterminating predators would require a massive effort that
would wipe out predatory species from barnacles to blue whales. Without the population control
provided by predators, some organisms would soon overpopulate,
Explain the phrase "only certain organisms can change solar energy into chemical energy," in the
underlined portion of the first paragraph. In your answer be sure to identify:
1)the type of nutrition carried out by these organisms
2)the process being carried out in this type of nutrition
3)the organelles present in the cells of these organisms that are directly involved in changing solar
energy into chemical energy
The phrase "only certain organisms can change solar energy into chemical energy," is about the plants which means producer organisms.
What is an example food chain?An example of this type of process is: plants generate their own food and are part of the feeding of insects, which are consumed by frogs. They serve as food for snakes, a source of nutrition for birds, which are consumed by decomposers.
Organisms of this level are classified as autotrophs, that is, they are living beings capable of producing their own food, not being necessary to feed on another living being. Plants and algae are organisms classified as producers.
