it's obviously D . it's a heritable change because the mutation in the sperm cell is gonna cause a mutation in the zygote
A mutation in the sperm cell will most likely result in heritable change ton the attributes of organisms.
Mutations that happen in vegetative cells such as skin, lung, and brain cells cannot be passed on to future generations.
Heritable mutations are those changes to the DNA sequence of sex cells. Changes elicited by such mutations are passed to future generations because they are germline based.
Sperm cells are sex cells. Thus, changes that occur as a result of mutation to sperm cells are most likely heritable.

by 50 percent?
3. Inferring Relationships Which fish in Lake Victoria do you think is higher on
the food chain
the cichlid or the Nile Perch? Explain your answer.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer:
92 daughter chromosomes.
Explanation:
There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.

Just for the fun of it, someone walking along the shore in Beaufort, South
Carolina, throws a bottle with a message in it into the sea. Some time later,
someone in Perth, on the west coast of Australia, finds the bottle.
Referring to map, trace the path the bottle probably took! Make sure to
reference specific currents on your path.
The currents that carry the bottle from South Carolina to Peth are the West Wind Drift and the South Equatorial Current.
According to the information provided by the map, it can be inferred that the bottle that is thrown into the sea in South Carolina, USA and arrived in Perth, Australia took the following route:
It traveled down the Atlantic Ocean from the United States to the West Wind Drift current. Once there, it is transported from the west to the east, passing through the lower part of Africa and Asia until it reaches the Indian Ocean. When it reaches the Indian Ocean it is carried by the South Equatorial Current with a northeast direction. In this direction it reaches the coast of Peth, Australia.

D.The sides are made of alternating nitrogenous bases, and the rungs are made of phosphate-sugar groups joined by hydrogen bonds
The sides are made of alternating phosphate-sugar groups, and the rungs
are made of complementary nitrogenous bases joined by hydrogen bonds
DNA which is also called Deoxyribonucleic acid contains genetic information
which are passed from the parent to offspring. DNA is made up of an
alternating phosphate-sugar group in which the sugar is deoxyribose.
The alternating phosphate-sugar group are located at the side of the ladder.
The rungs are made up of complementary nitrogenous bases joined by
hydrogen bonds. Example of nitrogenous bases include adenine, thymine,
guanine and cytosine.

Why are hydrogen bonding and popularity so important for water molecules?
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

Answer:
Its Point A
Explanation:
The following tracking model was created for Hurricane Ike on September 8, 2008. Map of Gulf Coast showing the forecasted path of Hurricane Ike on September 8, 2008. The storm’s current location, as of 5 p.m. on Friday, is just south of Cuba, over the Caribbean Sea. The “cone of probability” extends northwest. Point A is located along the Texas coast, right in the center of the cone’s widest point. Point B is located along the coast of Louisiana, toward the easternmost edge of the cone. Point C is located further east, along the coast of the Florida Panhandle. Point D is located on the border between Mexico and Texas, toward the southwestern-most edge of the cone. According to this model, at which point is the storm least likely to make landfall?

Answer:
animal
Explanation:
Animal: All components present. Plant: All components present. Virus: Only cell membrane present. Prokaryote: Cell membrane present, others absent.
Option (1) is correct.
Animal: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Animals are eukaryotic organisms with membrane-bound organelles and a well-defined nucleus.
Plant: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Plants are also eukaryotic organisms and share similar cellular structures with animals, including membrane-bound organelles and a nucleus.
Virus: Only a cell membrane may be present, depending on the type of virus. Viruses are acellular particles that lack organelles and a nucleus. They consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell's membrane.
Prokaryote: Cell membrane is present, but ribosomes, lysosomes, and nuclear membrane are absent. Prokaryotes, such as bacteria, lack a nucleus and membrane-bound organelles. They have a simpler cell structure, with genetic material located in the cytoplasm and ribosomes involved in protein synthesis. Lysosomes, which are membrane-bound organelles involved in digestion, are not present in prokaryotes.

Cell processes that increase the surface area of a cell are called:
Answer:
Answer below
Explanation:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly).Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration.These foldings too increase the surface area.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Non-motile cilia are structures in a cell membrane that also increase surface area. Non-motile cilia are like oars that push through the cell membrane. They are thinner and longer than microvilli. Non-motile cilia are also called primary cilia.

To read signs, you need to have good ________ . focal vision peripheral vision paracentral vision double vision
To read signs, one needs good peripheral vision. The capacity to see things that are beyond of one's direct line of sight is known as peripheral vision. It is the capacity to perceive things that are beyond of one's direct field of vision.
Because it enables a person to perceive items that are situated at the boundaries of their peripheral vision, this form of vision is crucial for reading signs.
For instance, it's crucial to be able to understand signs that are placed along the side of the road when driving. A person might not be able to see the signs and might miss crucial information without adequate peripheral vision. Aside from peripheral vision, clear focus vision is crucial for reading.
