Answer:

<em><u>D. Cytoskeleton</u></em>

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work. So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.

Zepler [3.9K]

Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).

<h3>What is secondary endosymbiosis?</h3>

Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.

According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.

The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.

ANSWER AND EXPLAIN PLZ:)

Rudik [331]

Answer:

The independent variable in the experiment is A. the jar covers.

Explanation:

The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.

The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Hope this helps!

Compare and contrast the ways of life of crustaceans and arachnids and explain how their body forms are adapted to their environ

Ede4ka [16]

<span>Insects are found in almost all ecosystems on Earth, with the rarity being oceans. While some species, such as coconut crabs, sand hoppers, woodlice and pill bugs dwell on land, crustaceans are generally found in water â€” and usually oceanic â€” regions. Adapting to their habitat, many insect species evolved wings â€” two pairs for most and one pair for others. A tracheal system is also present for breathing. Crustaceans, on the other hand, breathe using gill-like mechanisms.</span>

How does lack of water conservation affect the hydrological cycle

MArishka [77]

Human activity such as the burning of fossil fuels has an effect on the overall increase of the Earth's temperature. Raising the Earth's temperature means that there is an increase of evaporation, melting of land and sea ice, and impacts on other processes of the water cycle that adversely affect the climate on Earth.
