In the picture, there is a dark moth and light moth on each tree. If all the trees are dark colored
(without lichens) like the tree on the right, which moth is more likely to survive? DS
(1 Point)

Answers

Answer:

If all the trees are dark-colored  (without lichens) like the tree on the right, the moth that would most likely survive longest is the dark-colored moth.

Explanation:

This is because of natural selection (which means "A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.") The dark-colored moth is best adapted to its surroundings compared to the light-colored moth, and it will survive the longest (of the two) according to this definition of natural selection.

how does the gravitational force between two objects change if the distance between the objects increases?

Answers

Answer:

YES

Explanation:

As g ∝ 1/d² between two two components, further potential difference would result in lower gravitational pull. So the influence of gravitational pull among them also reduces as two things are isolated from the others.

Answers

30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.

31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.

32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

33.amino acids

For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein

34.Peptide Bonds

Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).

Genes are expressed according to instructions in traits.​

Answers

PLS TELL ME THE ANSWER NOWWWWWW >:(

Genes code for the production of specific proteins. These proteins lead to different traits. The correct option is a.

What are traits?

A trait, as it relates to genetics, is a unique feature of an individual. Genes, environmental factors, or a combination of both can influence traits.

Qualitative traits (such as eye color) and quantitative traits (such as height or blood pressure).

A gene is the most fundamental physical and functional unit of heredity. DNA is the building block of genes.

Some genes serve as blueprints for the creation of proteins. Many genes, however, do not code for proteins. Genes in humans range in size from a few hundred DNA bases to over 2 million bases.

Genes encode instructions for the production of specific proteins. These proteins result in various characteristics.

Thus, the correct option is a.

B) according to the law of superstition the youngest rock layers are at the bottom. C) The oldest known rocks on earth are approximately 4 million years old. D) earth is constantly changing.

Answers

Answer:

B

Explanation:

The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)

Hope this helps :)

The statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

What are the fossils?

The fossils are the preserved materials of the animals and plants, such as the skeleton, teeth, bones, imprints, and other parts stored in the different layers of the earth. These fossils are preserved in natural ways, not by humans, and they are helpful for the study of the different animals because some fossils give the idea of the connecting links, and they give the idea of the animals' living conditions in the early time.

Hence, the statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

What is cell?

Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
