Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.
Some desert plants respond to darkness by opening their flowers at night to lure in pollinators. In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.

1. For a mutation to affect evolution, it must:
a. Provide a benefit to the organism
b. Involve more than one chromosome
c. Be able to get passed from parent or offspring
d. Be neutral—neither help nor harm the organism
For a mutation to affect evolution, it must provide a benefit to the organism. Hence option A is correct.
In order for a mutation to have an effect on an organism’s progeny, it must: occur in the next generation’s cells and affect the inherited material, impact the environment, and generate diversity among species.
They result in novel proteins that allow organisms to adapt to environmental changes. Mutations that are beneficial are necessary for evolution to take place. Mutations that enhance an organism’s ability to survive or reproduce are likely to increase in frequency over time.

Antibodies are found in the blood plasma.
True
False
Answer:
True
Explanation:
Blood plasma contains antibodies, a type of protein that can fight a substance considered foreign to the host body. The body manufactures antibodies to correspond to naturally occurring antigens inherited through DNA. Foreign antigens occasionally introduced by way of pregnancy or blood transfusions will also cause the body to make antibodies.

During prophase I of meiosis, these pairs form a tetrad in a process called:
Answer:
Synapsis...
Hope that helps!
Explanation:
During prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination. Tetrad is formed with the help of the alignment of two homologous chromosomes.
What do you mean by Meiosis?Meiosis may be defined as a process where a single cell divides twice to create four cells comprising half the original amount of genetic information.
In prophase I of meiosis, the two homologous chromosomes align in such a way that it undergoes crossing over, which synthesizes four chromatids of two chromosomes and leads to the formation of the tetrad.
Therefore, during prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination.

Suppose that millions of years from now Australia moves to South America. Would Australia still have the same kinds of mammals? Explain your answer.
Answer:
Which best explains why Australia has life forms that do not exist anywhere else on Earth? Australia was separated from the other landmasses by geological forces. Scientists think that dolphins and whales may have evolved from a common ancestor.
Assuming that millions of years from now Australia moves to South America. Australia would not have the same types of mammals, because with the junction of the continents new conditions would suggest for animals to evolve.
What was the evolution of continents?Continental Drift is a theory that claims that, at one time, all the present-day continents formed just a single landmass, called Pangea. This supercontinent, thanks to the movement of the Tectonic Plates, fragmented several times until it provided the current shape of the land masses.
With this information, we can conclude that millions of years from now Australia will move to South America. Australia would not have the same types of mammals, as with the joining of the continents new conditions would suggest the evolution of animals.

What is a cell?
The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.
Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.
Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.
