Answer:

a is the answer the the following question

Answer:

Yes, it should be considered a pollutant

Find the reason below

Explanation:

A pollutant is any substance that poses threat or causes harm to the sustainability of the environment. As rightly stated in this question, carbon dioxide (CO2) is a naturally occuring gaseous constituent of our atmosphere. It is vital to both animal and plant life as it is utilized by plants to synthesize their food (glucose), which is the starting point for the flow of energy.

Although CO2 plays a major role in sustaining life, it is also a major cause of GLOBAL WARMING. Carbon dioxide is considered the most important greenhouse gas as it has the ability to trap and emit heat, contributing to the global rise in atmospheric temperature. This causes a lot of harm and environmental disturbance, hence, CO2 despite its beneficial purpose, should be considered a POLLUTANT.

1.) True

The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.

2.) True

While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to.

Hope this helps you, and have fun with whatever it is you are doing with your camera.

Answer:

Explanation:

A gamete is a haploid reproductive cell that fuses with another gamete of opposite strain to form a diploid

zygote.

A zygote is a cell formed by the fusion of the male and female gamete before it undergoes division.

gametes are haploid while a zygote is diploid.

There is exchange of genetic material during sexual reproduction and fusion of gametes. Meiosis is also involved.

The opposite occurs in asexual reproduction and mitosis is involved instead.

Asexual reproduction is common in prokaryotes eg bacteria.

Answer:

The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.

Explanation:

The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.

In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.

Answer:

Choice D

Explanation:

When you translate the RNA, you replace C’s with G’s (and vice versa) and A’s with U’s (also vice versa). So, you get GUU UUA CGC UAG. Then you read the codon chart to get your answer. Hope it helps :)

The sequence of the amino acids which is being produced when this RNA is translated is Val - Leu - Arg - Stop. Thus, the correct option is D.

Codon can be defined as the sequence of three consecutive nucleotides in the nucleic acids such as a DNA or RNA molecule which codes for a specific amino acid. Certain codons are responsible for the signal of the start or end of the translation process.

Codons are universal in nature throughout the different living organisms. There are about 64 different codons which codes for 20 standard amino acids in the cell. There are three stop codons in the genetic code which stop the process of translation of protein molecules including UAG, UAA, and UGA.

The sequence of the amino acids which can be produced when this RNA is translated 5'-CAA AAU GCG AUC-3' will be Val - Leu - Arg - Stop.

Therefore, the correct option is D.

Answer:

Forests

Explanation:

Forests have also sanitary influences upon environment due to the production of oxygen through photosynthesis.

The study of the environment is called ecology. There are two types of factors for an ecosystem and these are a biotic and abiotic factors.

The correct answer is light

The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.

According to the question, the most influential factor which affects the environment is light as all the plants directly depend on the light for the formation of food and all the other species are dependent on plants either directly or indirectly.

Hence, the correct answer is light.

Answer:

No, since different genes will exert varying degrees of influence on the trait

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.

Answer:

the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.

Clouds can block light and heat from the Sun, making Earth's temperature cooler

Answer:

D

Explanation:

Based on the terms provided, the energy transformation taking place in the plant in the photograph is: Solar energy → Chemical energy This is because plants undergo a process called photosynthesis, where they convert solar energy (sunlight) into chemical energy stored in glucose molecules. The correct option is B.

The transformation of energy from one form to another is known as an energy transformation. Every second of the day, energy is transformed somewhere. Energy can be expressed in a variety of ways, including electrically, thermally, nuclearly, mechanically, electromagnetically, sonically, and chemically.

The process of photosynthesis is taking place. The plant is converting solar energy (from the sun) into chemical energy in the form of glucose (sugar). This is an example of a transformation from one form of energy (solar) to another (chemical).

Therefore, the correct option is B.
