The fossil record is used as evidence that supports which of the
following descriptions of the evolution of life on Earth?

Answer:

1. Integumentary System

2. Digestive System and Endocrine System

Explanation:

An organ system combines multiple organs to perform one or more biological functions.

The integumentary system which human skin, is an organ system that protects the outer body. So the stretch marks women experience during pregnancy are evident on the skin, and since it was mentioned in the question that "A mother's body undergoes many changes to accommodate the developing fetus during pregnancy" it can be concluded that the skin stretched due to fetus development.

The digestive system here, the liver, can get disordered by a liver disease known as Cholestasis, which alters the flow of bile produced by the liver for digestion and can lead to bilirubin buildup poisoning blood and causing itchiness that can be experienced during pregnancy.

The Endocrine system is the Hormone center of the body, it affects the mood, and can cause itchiness too.

True

Explanation:

Carrier proteins are the proteins which can help move some substance down their concentration gradient and they can do that by changing their shape while transporting substances across cell membranes. They are responsible for active transport of materials into or out of the cells.

Answer:

DNA REPLICATES

Explanation:

During G1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase.

Answer:

O Feathering

Explanation:

Feathering refers to the technique by which large flowers are cut into small pieces, which are then used to create smaller flowers. Feathering consists of removing the petals and wire the petals in order to create a smaller form. Carnations are a type of flower in which feathering is applied. This process was widely used by florists in the past but currently is uncommon due to the excessive time and labor involved in this technique.

Answer:

Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.

Explanation:

Variation definition- any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behavior, learning and mental ability, and other obvious or measurable characters.

The brightly colored cardinals are able to survive and reproduce because of variation in a species. Your question states "Variations within a species", so with that clue we can eliminate A and C (examples of competition) And B does not mention variation in a species. So we can conclude that D is the correct answer, since the brighter cardinals are able to survive and reproduce better than the darker cardinals, this is an example of Variation.

Due to variation, brightly colored cardinals are better able to survive and reproduce than darker cardinals. The correct answer is d) Brightly colored cardinals are better able to survive and reproduce than darker cardinals.

Any difference between cells, individuals, or populations of organisms of any species that result from genetic variations or from the influence of environmental circumstances on the manifestation of the genetic potentials (phenotypic variation) is referred to as variety. Physical characteristics, metabolism, fertility, mode of reproduction, behavior, learning, and mental capacity, and other evident or measurably different characteristics can all vary.

Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this overproduction is that those people who have the highest level of environmental genetic fitness will have kids who are better able to compete in that environment.

Variation within a species allows for the survival and reproduction of the vividly colored cardinals.

Therefore, the correct answer is d).

It has a similarity because the non-native squirrel is part of the interactions in the natural world. It shows the contrasts and comparasions of animal life and other interconnections.

Explanation:

bush burning - more carbon released into the atmosphere

deforestation - reduction of population of specific species of trees

crop rotation - more nutrients conserved in the soil

afforrestation -less amount of carbon in the atmosphere(cleaner air)

Answer:

Most cattle in the US have a fodder that is composed of at least some forage (grass, legumes, or silage). In fact, most beef cattle are raised on pasture from birth in the spring until autumn (7 to 9 months). For pastured animals, grass is usually the forage that composes the majority of their diet.

Food for the cattle is know as Fodder

Answer:

Bad form.

Explanation:

Bad form of ozone causes breathing difficulty due to its availability near the surface of earth and its composition. Ozone is not emitted directly into the air, it is created due to the chemical reactions between oxides of nitrogen and volatile organic compounds. When these pollutants react with each other in the presence of sunlight, ozone is produced which leads to difficulty of breathing as well as damages the vegetation so this ozone is considered as bad ozone.

Explanation:

Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.

Explanation:

The factual statement is Asexual reproduction produces offspring that are identical to the parent. Asexual reproduction is a type of reproduction in which offspring are produced from a single parent without the fusion of gametes. Hence option A is correct.

This means that the offspring inherit all of their genes from the parent, and are therefore genetically identical to the parent.

Sexual reproduction, on the other hand, is a type of reproduction in which offspring are produced from the fusion of two gametes, one from each parent.

This means that the offspring inherit genes from both parents and are therefore not genetically identical to either parent.

Therefore, option A) Asexual reproduction produces offspring that are identical to the parent is correct.

Answer: it's c

Explanation:

The statement that explains how producers are dependent on consumers for their survival is "Consumers produce carbon dioxide for producers to use during photosynthesis," which is present in the option C.

The ecosystem must have both the consumer and the producer, as neither can survive if one gets eliminated from the ecosystem. The producer makes oxygen and glucose by taking the carbon dioxide that is released by the consumer, and in an ecosystem, there are many types of consumers, such as herbivores and carnivores. The consumer depends upon the producer for oxygen and food, while the producer depends upon the consumer and decomposer too.

Hence, the statement that explains how producers are dependent on consumers for their survival is "Consumers produce carbon dioxide for producers to use during photosynthesis," which is present in the option C.
