A secondary consumer that obtains its energy from the consumption of animals.
Who are secondary Consumer?Organisms that consume primary consumers for energy are known as secondary consumers. Herbivores, or species that only consume autotrophic plants, are always the main consumers.
Secondary consumers, however, might either be omnivores or carnivores. Omnivores consume both plant and animal stuff, while carnivores solely consume other creatures. Whatever a secondary consumer may be, it still needs to eat primary consumers to thrive.
Secondary consumers can be found in almost every environment on earth and occur in a wide variety of sizes and shapes. The severe habitats that secondary consumers reside in include icy tundras, parched savannahs, and arctic lakes.
Therefore, A secondary consumer that obtains its energy from the consumption of animals.

Since animal cells don’t have a cell wall, what would happen if they loss water indefinitely?
Answer:
Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die.

C. The objects are different substances because their volumes are different.
D. The objects are the same substance because they have the same density
The true statement is that the objects are different substances because their densities are different.
Density is an intrinsic property of matter. It does not depend on the amount of substance present. It is a characteristic of substances. If two substances are the same, they must have the same density.
Considering the information presented here, the cube and the marble are different materials hence they have different densities.

Why is it important that meiosis produces a haploid cell? What would happen to subsequent generations if mitosis were used to produce gametes?
Answer:
It is important that meiosis produces a haploid cell because it prevents the number of chromosomes from doubling each generation. If mitosis were used to produce gametes the subsequent generations would be diploid so in the next generations the normal amount of chromosomes would double meaning each subsequent generation would double the number chromosomes again and again.
Explanation:
Meiosis
- the process by which the number of chromosomes is halved during the formation of gametes.
- In human cells, for example, 46 chromosomes are arranged in 23 pairs. Therefore, human cells are diploid i.e. they have two sets of 23 chromosomes per set. During generative reproduction, the sex cells of the parent organism unite with one another and form a fertilized egg. In this situation, each sex cell is gamete. Gametes from haploid human cells, from Greek haplos, which means "single." This term implies that each gamete contains a set of 23 chromosomes in humans. When human gametes unite with each other, the original diploid condition of 46 chromosomes is rebuilt. Meaning cells containing a diploid number of chromosomes are converted into four cells, each of which has a number of haploid chromosomes. In human cells, for example, reproductive cells containing 46 chromosomes produce four cells, each with 23 chromosomes.
Mitosis
- the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus. Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
-In each cycle of cell division, two daughter cells are formed from the parent cell. The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.

Meiosis' production of haploid cells is crucial because it stops the chromosome count from doubling every generation.
What is meiosis?Meiosis is a reductional division. The number of chromosomes would double in the following generations if mitosis were utilized to make gametes, making the subsequent generations diploid and doubling the number of chromosomes in each successive generation.
Meiosis is the process by which the number of chromosomes is cut in half as gametes are developing.
For instance, there are 23 pairs of 46 chromosomes in human cells. Human cells therefore have two sets of 23 chromosomes each, making them diploid.
Therefore, Meiosis' production of haploid cells is crucial because it stops the chromosome count from doubling every generation.

Briefly summarize the main stages of human evolution beginning 410 million years ago with the evolution of amphibians.
Biologically, man is defined as primate by the species Hom.o sapiens, of which the only living subspecies is Hom.o sapiens sapiens. It is quite clear that man's closest living relatives are the African apes, chimpanzees and gorillas, and it is almost certain that chimpanzees are more closely related to us than to gorillas.
The early development of the human race took place in Africa. All fossils from our evolution from 7 million years ago to 2 million years ago that were found lived in Africa. Sometime almost 2 million years ago, however, human-like creatures of the genus Hom.o began to spread around the world, and fairly quickly populated large parts of Asia and Europe, all the way to Indonesia and China. Regarding the geographical origin of modern man, there are two main explanatory models.
According to the Out of Africa hypothesis, modern humans evolved in Africa and from there spread out over the world, competing with other hominids. The multiregional hypothesis instead claims that humans evolved in parallel from several at least partially isolated populations of hominids.

In Ken Baum’s piece, which one do you think is the strongest policy argument against physician participation in a legally authorized execution?
The participation of a physician in a legally authorized execution goes against the oath taken by the professional, and this is the main argument against their participation.
A physician is a term used to describe a doctor who has obtained a university degree to practice medicine. Once completed their university career and in order to obtain their medical license, Physicians must take an Oath.
The Oath in question is the Hippocratic oath. Among many things, this oath tells the professional to act in a certain manner, always in the best interest of the patient in question. This is directly contradicted by the actions of a physician that participates in the legally authorized execution of a human being and is one of the main reasons against this participation.
Though I could not locate Ken Baum’s piece online to provide direct evidence, I have given a popular argument against the physicians' participation in this matter.
