It is a fact that the human activities are changing the atmosphere. The atmosphere is warming up naturally, bu the human activities are increasing that process, which can create lot of problems in the future. The scientists can come in very handy and helpful for this problem. The scientists are constantly trying to find new solutions that are eco-friendly, and that will minimize and eliminate the human effect on the atmosphere. Lot of new inventions have been developed, and all of them have been with the purpose to cool down, or at least leave the natural process of warming of the atmosphere, while stopping the human influence. Unfortunately, it is not the problem in the technology invented by the scientist for this problem to be solved, but it is the governments and people around the world that are not willing to implement them.

Chlorophyll is the primary green pigment responsible for plant color. The molecule appears green because it absorbs all wavelengths of light except for green, which it reflects back for us to see. In the autumn, trees and plants undergo changes in their pigments. Which of the following best describes why we observe many trees change their color to red, orange, or yellow in the autumn?

A. As chlorophyll becomes colder, it changes its color from green to red, orange, or yellow.
B. Chlorophyll breaks down, exposing other pigment molecules we normally don't see.
C. The soil produces different nutrients in the winter that are absorbed into the plant and cause color change in the leaves.
D. Tree leaves stop producing chlorophyll in cold temperatures and produce other pigment molecules.

Answers

The answer would be B.

Chlorophyll breaks down and turns into other pigments such as carotenoids. The chloroplasts transform into chromoplasts where these pigments are stored.

Hope this helps:)

Answer:

The correct answer is option B, that is, chlorophyll breaks down, exposing other pigment molecules we normally don't see.

Explanation:

Leaves are colored because of the presence of the molecules known as pigments. Chlorophyll is the pigment, which makes the leaves to appear green. Chlorophyll is an essential element for plants as it helps the plant to synthesize food with the help of sunlight.  

At the time of summer and spring, when there is enough amount of sunlight available, the plants produce loads of chlorophyll pigment. However, in autumn when it begins to get cooler, some of the plants stop producing chlorophyll, and those plants dissociate chlorophyll into smaller constituents. With the diminishing of chlorophyll, the other pigments begin to show their colors, and thus, the leaves turn red or yellow at the time of fall.  

HELP!! Are the Earth's ocean floor and continents the same age geologically? Why or why not?​

Answers

Answer:

No, the ocean floor is much younger because new crust forms there.

Explanation:

The Earth's ocean floor and the continents are not the same age geologically. The ocean floor is much younger because new crust forms there. New crust is usually formed at the oceanic spreading centers. This process takes place when the oceanic plates pull apart, and molten lava wells up from the mantle to fill the openings. This effectively functions as a recycling system for the oceanic lithosphere.

Option B: The chromosome is the cell structure made of DNA that gives the master instructions for the cell. Chromosomes carry an organism's genetic code and are crucial for DNA replication and distribution. They ensure that each new cell receives the correct genetic information during cell division.

The structure made of DNA that gives the master instructions for the cell is the chromosome. Chromosomes are found in the nucleus of eukaryotic cells and they carry the genetic information necessary for the growth, development, and functioning of organisms.

To elaborate:

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. During cell division, chromosomes ensure that DNA is accurately copied and distributed in the vast majority of cell divisions.The DNA in chromosomes contains genes, which are specific sequences of nucleotides that code for proteins and other products necessary for cellular functions.The chromosome is crucial because it organizes the DNA into manageable units, allowing for accurate replication and distribution during cell division, ensuring that each new cell receives the correct genetic instructions.

For example, in humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Each parent contributes one chromosome to each pair.

What is a clade?

A. A group of organisms with a shared ancestor

B. A trait that an ancestor did not have

C. A group with no shared traits

D. A trait that was passed along

Answers

Answer: A. A group of organisms with a shared ancestor

Explanation:a group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics.

Clades are important because they represent a natural way to classify organisms based on their evolutionary relationships. A clade includes all of the organisms that descended from a common ancestor, and can be further divided into smaller clades based on more recent shared ancestry.

What are clades identified as ?

Clades are often identified by certain shared characteristics, such as genetic traits or physical features, which are known as "synapomorphies."

Synapomorphies are traits that evolved in the ancestor of a clade and were then passed on to all of its descendants. By looking for synapomorphies, biologists can identify the members of a clade and distinguish them from other groups of organisms that do not share those traits.

One of the key benefits of organizing organisms into clades is that it allows scientists to make predictions about the characteristics of organisms that have not yet been discovered. By knowing the traits of a clade's common ancestor, scientists can infer what traits its descendants are likely to have, and can use that information to guide their search for new species.

By organizing organisms into clades, biologists can gain insight into the history of life on Earth, and better understand the relationships between different groups of organisms.

Thus,  Clades also help researchers better understand the patterns and processes of evolution, and provide a framework for studying the diversity of life on Earth.

A good experiment usually has into account all the variables that can affect the variable to be measured (i.e., the dependent variable).

Thus, it is more suitable to test a hypothesis (either reject or confirm) only when having into account all variables that might affect the experimental group in normal conditions.

A good experiment also uses a control group in order to make comparisons with the experimental group.

A control group is defined as an experimental group consisting of subjects/individuals who do not receive the experimental treatment.

Explanation:

Since albinism is a recessive characteristic, let's assume that it has the "aa" alleles, so an individual who does not have albinism would have the "AA" alleles if he were homozygous and "Aa" if he were heterozygous.

If an albino (aa) female were to mate with a heterozygous, non-albino (Aa) male, we could fill in a punnet squad to determine what the offspring would be like. As we can see in the punnet square attached below, the result of this crossing would be 50% offspring "Aa" and 50% offspring "aa".

Answers

The answer is a.Algae
Final answer:

The first embryophytes were bryophytes, which include mosses and liverworts. They are considered the first land plants to have the capacity to form an embryo within protective structures. However, they lack the vasculature system seen in higher-order plants.

Explanation:

The first embryophytes in the plant kingdom were bryophytes. Embryophytes are land plants that include all green plants, ranging from mosses to lush green trees. The term 'embryophyte' primarily refers to plants that are capable of forming an embryo within protective structures. The first plants to evolve this ability were bryophytes, which include mosses and liverworts.

These plants don't possess a vasculature system as seen in higher-order plants (pteridophytes, gymnosperms, angiosperms), and they don't produce seeds. Bryophytes are mostly distinguished by their life cycles, characterized by dominant gametophytes stage. They reproduce via alternation of generations where the dominant phase is the haploid gametophyte, which is contrasted with the vascular plants where the sporophytes are the dominant stage.
