If there weren't alleles for different traits, but rather only one version of a gene for different traits, how would humans be different?

Answers

Answer 1

Answer:

Humans would look exactly alike

Explanation:

An allele which is a variation of a gene which expresses a particular trait(Phenotype).

For example, if humans have a gene for eye color but has different alleles for the color being black or brown for example, their phenotypes are different since the alleles are different.

But, if the alleles for the eye color are all the same, the eye color and every other phenotype would be the same. So, there would be no variations in eye color, height, color of skin etc. So, all humans would thus look alike having one set of genes for the different traits.

Explain binary fission in amoeba​

Answers

Answer:

Binary fission is the most common method asexual reproduction employed by amoeba. During this stage, amoeba stops its movement by withdrawing its pseudopodia and forms a spherical shape. The genetic material is divided by the process of mitosis, after the division of cytoplasm follows the division of the nucleus, resulting in two daughter cells which are identical clones obtained by parent cells.

MARK ME AS BRAINLIEST PLEASE

Answer:

Amoeba is a unicellular organism, and just like bacteria, it reproduces through binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells. In this method, two similar individuals are produced from a single parent cell

describe how energy for the photosynthesis reaction is gained by plants (2)

please help ​

Answers

Answer:

Plzzzz answer fast......

The energy for the photosynthesis reaction is gained in the first stage of the reaction.

There are 2 stages in photosynthesis:

The light-dependent stageThe light-independent stage

During the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.

The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.

The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

Answers

Explanation:

Algae, Mosquito larvae, Minnows, Trout, and Herons are arranged in the following pattern in a food chain.

What is a food chain?

A  food chain is an arrangement of organisms where energy flows from through lower organism to higher organism. Each organism in the chain transfers energy to the other organism present at higher order and the flow of energy goes on.  Biotic factors, algae, mosquito larvae, minnows, trout, and herons are arranged in the following sequence in the food chain.

Algae are the primary producers in aquatic ecosystems which are eaten by mosquito larvae, which are then eaten by minnows. Minnows are then eaten by trouts. Herons, being the largest predator feeds on the trout.

Each organism in the food chain obtains energy from the organisms present at lower trophic level. However, the energy flow decreases at each trophic level, therefore, the organism at higher trophic level receives the less amount of energy.

Therefore, the food chain is created in the following order: Algae, Mosquito larvae, Minnows, Trout, and Herons.
