Genes code for specifically structured proteins. The majority of genes have the necessary instructions to produce the useful molecules known as proteins, hence option D is correct.
The segment of DNA needed to make one protein is known as a gene, because they code for proteins consisting of hundreds or thousands of amino acids, genes often have hundreds or thousands of base pairs.
The ribosome, a specialized complex that "reads" the sequence of mRNA nucleotides, interacts with the messenger RNA (mRNA). A codon is a group of three nucleotides that typically codes for one specific amino acid.

How was early Earth's atmosphere different from today's atmosphere?
Answer:
The early Earth was very different from our Earth today.
Explanation:
Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.
Answer:
The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.
How has the Earth's atmosphere changed over time?
Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

What is Earth's atmosphere made of?
Answer:
Explanation:
Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent
explain whether the following statement is true or false: “All arteries carry blood with oxygen and all veins carry blood with carbon dioxide.”
Answer:
False
Explanation:
Important parts of circulatory system are heart, capillaries, veins, and arteries. The arteries are responsible for carrying red blood from heart and deliver oxygen to capillaries. Then capillaries deliver the waste carrying blood or deoxygenated blood to veins back to the heart.
But not all arteries carry blood with oxygen, the pulmonary arteries carry deoxygenated blood and not all veins carry blood with carbon dioxide, the pulmonary veins carry blood with oxygen.
Hence, the given statement is true.

How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

The cell theory is a scientific explanation about the characteristics of cells in living things discovery of cells occurred in the 1600s which piece of equipment my students in science class used to investigate the cell theory
Answer:
Then, what is the question????
In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.
What is Microscope?A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.
Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.
Thus, in 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.

Answer:
1. Cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly, and their shapes help them carry out these roles effectively. The following cell types all have unusual shapes that are important for their function. 2. Stem cells are cells with the potential to develop into many different types of cells in the body.

Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.

You learned in the reading that some symbiotic relationships are helpful and some are harmful. Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition
Answer: Parasitism, Predator-Prey, Competition
Explanation:
The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Binary fission is a type of asexual reproduction observed in bacteria, in which one cell divides into two daughter cells.
What is binary fission?During binary fission, there is no involvement of two parents and also there is no gamete formation occurring, so it is categorized into asexual reproduction.
There are several steps during binary fission, firstly bacteria replicates its DNA, secondly, it grows and increases the number of a cell organelle, now it segregates DNA into two parts, at the end splitting this large cell.
In DNA replication bacteria uncoils its chromosome and copy this genetic information to transfer it to subsequent generations.
Therefore, replication, cell growth, segregation, and splitting of the cell are stages of binary fission.
