According to the theory of natural selection, why are some
individuals more likely than others to survive and reproduce?
A
Some individuals pass on to their offspring new
characteristics they have acquired during their lifetimes.
B
Some individuals are better adapted to exist in their
environment than others are.
с
Some individuals do not pass on to their offspring new
characteristics they have acquired during their lifetimes.
Some individuals tend to produce fewer offspring than others
in the same environment.

Answer:

double-stranded DNA are tightly looped, coiled, and folded so that they fit easily within the cell. ... In both eukaryotes and prokaryotes, this highly compacted DNA is then arranged into structures called chromosomes.

Explanation:

Moist soils, Damp walls and mud regions where the water is not in limiting conditions are best suited for the growth of non vascular plants as they can not absorb and transport water to taller aerial organs.

Answer:

Monotremes, marsupials, and placentals are the three animals that could match this phylogenetic tree.

Explanation:

Monotremes, marsupials, and placentals belong from  a common ancestor. Those organisms which have one common ancestor are also called monophyletic. These animals have some changes which occurs with the passage of time but most of characters are similar to each other. In placentals animals placenta is present while in Monotremes and marsupials this placenta is absent.

Answer:

Oil and gas are used widely in modern life. Oil fuels the cars, trucks and planes that underpin modern economies and lifestyles. Nearly all pesticides and many fertilisers are made from oil or oil byproducts. Gas provides electricity and is also used for cooking, heating houses and buildings, and heating water.

Digitizing means converting something into digital form.

Digitizing image means converting any image into digital format and the image will be organized into bits or pixel. The bits or numbers are then processed by a computer and output is generated as visible-light image,

There are several advantages of digitizing images and one cam easily tansmit images:

Hence, digitizing image is common now a days to transmit images of better quality in easy way.

Amphibians, like frogs and newts, have a slightly more complicated life cycle. They undergo a metamorphosis (a big change): they are born (either alive from their mother or hatched from eggs)

Answer:

Control group - the plant group which has not received the fertilizers treatment.

Experimental group- the groups treated with different varieties of fertilizers.

Independent variable- amount of water and fertilizers

Dependent variable- growth of plants

Explanation:

A scientific experiment is performed in a way that the experimental samples are classified into the control and experimental groups. Also, the experiment involves various variables to be studied which can be classified as an independent variable and dependent variable.

In the given question, the experimental samples are:

1. Control group- The samples which are not provided with the variable being studied like the experiment is performed to test the effect of fertilizers and "the plant group which has not received the fertilizers treatment" can be considered the control group.

2. Experimental group- the samples in which the variable to be studied are provided with that is "the groups treated with different varieties of fertilizers."

In the given question, the variables are:

1. Independent variable- the variable which can be changed or modified or can change on their own like "amount of water and fertilizers" in the experiment.

2. Dependent variable- the variable which is being tested, can be measured and is dependent on an independent variable like the " growth of plants"  in the experiment.

Answer:

Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.

Answer:

B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Explanation:

Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Hope that answers the question, have a great day!

Answer: Option A, C and D.

Explanation:

Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.

If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures

But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.

Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.

They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,

Explanation:

Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.

But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.
