Which of the following examples of an ecological study involves the ecosystem level of organization?A. The effects of human activities on biogeochemical cycling
B. The effects of a disease on population size
C. The effects of an invasive plant species on bird nesting sites
D. The effects of competition on survival

Answers

Answer 1

Answer: the closest answer to being correct is A, because ecosystem involves biotic and abiotic. and since humans are biotic and the cycle is abiotic. it is on the ecosystem level! :D

Do you think all organisms use the same behaviors to reproduce?

Answers

Answer: A species includes all organisms that can mate with one another to produce sexually fertile offspring. No individual organism lives forever. Therefore, reproduction is essential to the continuation of every species. Some organisms reproduce asexually and other organisms reproduce sexually.

4. Some cells, such as human nerve and muscle cells, contain many more mitochondriathan do other cells, such as skin cells. Infer why some cells have more mitochondria
than others. (SB1a)
A. The cells divide more frequently.
B. The cells use more energy.
C. The cells store more nutrients.
D. The cells degrade more proteins.

Answers

Some cells have more mitochondria because the cells use more energy. The correct option is B.

What are mitochondria?

Mitochondria are the powerhouse of the cell. It is a long cylindrical organelle. Some cells contain more mitochondria than others because they require more energy. The mitochondria store energy for the function of the cell.

So, for example, the muscle contains a lot of mitochondria, as does the liver, the kidney, and, to some extent, the brain, which runs on the energy that those mitochondria make.

Depending on the function of thecell, several mitochondria are frequently found in one cell. Mitochondria, like other organelles, are found in the cytoplasm of cells.

Therefore, the correct option is B. The cells use more energy.

Ralph's wants to breed two of his prize bulldogs. For the dominant alleles, he has selected small ears (E) and a curly tail (T). Linus, the male bullbog, is homozygous dominant for both traits. Lucy, the female, is heterozygous dominant for both traits. A. What are Linus's and Lucy's genotypes?
B. What percent of their pups will have small ears and curly tails?
C. What percent will have large ears (e) and straight tails (t)?

Answers

Answer:

a) Linus's genotypes - EETT

Lucy's genotypes- EeTt

b) 100 percent of their pups will have small ears and curly tails

c) 0 percent of their pups will have large ears (e) and straight tails (t)

Okay, so we have one homozygous, the prefix "homo" means "same" and we know that the male's genotype is dominate, so with the prefix "same" or "homo" we know the male's genotype must be EE, and TT. We also know that the female's genotype is heterozygous, and knowing that "hetero" means opposite, we know that she has the two opposite types of genes Ee and Tt
