Dafna11 [192]

Answer:

Plant-eating animals are called PRIMARY CONSUMERS.

Explanation:

In an ecosystem, consumers are heterotrophic organisms that can not make their own food. They rather depend on producers or other consumers for food and nutrition. The organisms that derive their nutrition directly from plants are called primary consumers. They are also called herbivores as they feed on plant and plant products. For example, deer graze grasses. This makes deer a primary consumer and a herbivore.

The chloroplasts of flowering land plants typically contain at least two photosynthetic pigments, chlorophyll a and chlorophyll

andrezito [222]

Answer:

a. In chlorophyll photosystems, the photons excite electrons that are transferred from donor to acceptor molecules in a process that involves oxidation-reduction reactions

b. As negative controls could be produced targeted mutations in genes encoding for enzymes that are not involved in the growth and in the photosynthetic activity

c. The plants that have many classes of photosynthetic pigments absorb light in different ranges of the visible spectrum, thereby it may confer an adaptive advantage to these plants

Tyra created a chart that compared DNA and RNA for her science class.

KATRIN_1 [288]

Answer:

Okay, 3 of the answer choices on this are wrong. The only correct answer is "DNA remains in the nucleus while RNA leaves the nucleus."

Explanation:

1. DNA is single-stranded while RNA is double-stranded

- INCORRECT. This is the opposite. RNA is single-stranded, whereas DNA is double-stranded.

2. DNA remains in the nucleus while RNA leaves the nucleus.

- This is true because the RNA must leave the nucleus to undergo translation into a ribosome in the cytoplasm.

3. DNA contains a ribose sugar while RNA contains a deoxyribose sugar.

- INCORRECT. This is the opposite. DNA contains deoxyribose sugar, whereas RNA contains ribose sugar.

4. DNA has bases of A, G, C, and U while RNA has bases of A, G, C, and T.

- INCORRECT. This is the opposite. DNA have bases of A, G, C, T, whereas RNA has bases of A, G, C, U. RNA sequences never have the bases of Thymine (T) as the same goes with DNA sequence that does not have the base of Uracil (U).

Honestly, I don't if the question are selectable choices or only one choice answers. There are three wrong answers and one correct answer.

How are plants of the savanna's highly specialized to grow in this environment of long periods of drought?

dexar [7]

Answer:

In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).
