A is an enzyme,B is substrate, and yes, protein
Explanation:
Budding and sporulation are forms of
A. asexual reproduction
B. binary reproduction
C. artificial reproduction
D. sexual reproduction
a. Asexual reproduction
Answer:
Explanation:
Asexual reproduction can be defined as a type of reproduction, in which new organisms are produced from a single parent without fusion of gametes. Offspring produced by asexual reproduction are identical to parent organisms as they have same genetic composition.
Both budding and sporulation are types of asexual reproduction. Budding can be defined as a process by which offspring develops from an outgrowth (known as bud) formed in parent organism due to cell division. Sporulation involves formation of spores from a single vegetative cell that develop into new organisms.
Thus, the correct answer is option (A).

how do the cells in meiosis differ from the cells in mitosis?
A. Cells in mitosis divide into new cells
B. Cells in meiosis go through one cycle of cell division
C. Cells in meiosis have unique genetic information
D. Cells in mitosis go through cycles of cell division
Answer:
C. Cells in meiosis have unique genetic information
Explanation:
Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.
The cells in meiosis differ from the cells in mitosis in the sense that cells in meiosis have unique genetic information.
Meiosis and mitosis are both types of cell division that occur in living organisms.
Further Explanation:
The statements that is NOT true about Mitosis and meiosis is
"The cells resulting from meiosis are diploid and the cells resulting from mitosis are haploid."
Further Explanation:Cell divisionCell division is the process in which cells undergo division to form other new cells.
There are two types of cell division;
Mitosis Division Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.The daughter cells have equal number of chromosomes as the parent and are identical to the parent, they are therefore diploid cells.This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.Meiosis divisionMeiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.In meiosis the daughter cells have half the number of chromosomes as the parent cells, thus known as haploid cells.Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.Meiosis occurs in two phases, that is, meiosis I and meiosis IIDuring the process of meiosis several processes occurs that cause genetic variation among organisms.These processes include, crossing over, independent assortment of genes, among others.Differences between cell mitosis and meiosis Mitosis occurs in the somatic cells while meiosis occurs in the gamete cells.Mitosis occurs in a single phase while meiosis occurs in two phases, that is, meiosis I and meiosis II.Mitosis involves formation of two daughter cells after cell division while meiosis forms four daughter cells after division.Daughter cells formed during mitosis are diploid while daughter cells formed during meiosis are haploid.Meiotic cell division causes genetic variation among organisms through processes such as crossover, while mitotic division does not enhance genetic variation.Cells in meiotic division have unique genetic information that is passed from the parent organisms to the offspring through when gametes from two parents fuse.Keywords: Cell division, mitosis, meiosis, crossing over, genetic variation, diploid cells and haploid cells.

Which describes the function of the human sperm cell’s structure?
There are trillions of cells within the human body, many of which are specilalized to perform specific functions. Red blood cells contain no nucleus or other organelles so allowing room for the oxygen carrying haemoglobin, smooth muscle cells are elongated and can shorten to allow for muscle contraction. Within all cells (except the RBCs) are organelles such as the nucleus and mitochondrion, and these organelles perform functions that are essential to life.
Answer:
The tail allows it to travel to the egg.
Explanation:
The structure of the sperm is divided into three parts head, body and tail. The head region consists of many enzymes and the tail region of the sperm helps in providing mobility to the sperm.
The structure of tail adds propelling movement by whipping and undulating the sperm. The sperm moves through the reproductive tract to reach the egg.

What type of cells have a cell membranes
All Prokaryote and eukaryote cells have plasma membranes.
Both prokaryotes and eukaryotes have cell membrane. Cell membrane is another name for plasma membrane.
What is cell membrane?Cell membrane is another name for plasma membrane. Both prokaryotic and eukaryotic cells have a plasma membrane, which is a double layer of lipids that separates the inside of the cell from the external environment. The majority of this double layer is made up of phospholipids, which are a type of specialized lipid. The plasma membrane, like all cellular membranes, is made up of both lipids and proteins. The phospholipid bilayer is the membrane's fundamental structure, forming a stable barrier between two aqueous compartments. The semi-fluid living matter contained in the cell is called protoplasm (or simply plasm). This living matter or plasm is contained within the plasma membrane, a biological membrane.

Three generations of a family afflicted with hemophilia are illustrated in the pedigree chart. Family members used the pedigree chart and the laws of genetics to predict the occurrence of the disease. From the information in the chart, one can determine that hemophilia is
A) sex-linked and occurs more in males than females.
B) autosomal and occurs equally in males and females.
C) sex-linked and no pattern of inheritance can be predicted.
D) autosomal and occurs more frequently in males than females.
Answer:
The answer is A. Sex-linked traits are more often expressed in males because they are typically carried by the X chromosome and they are also typically recessive. Males only inherit one X chromosome, so if the one they inherit is linked to the disease, they will express it no matter what. Females, on the other hand, can be carriers if they inherit one X chromosome with the disease. This is because their other X chromosome can be normal, which would dominate the expression of the disease on their other X chromosome.

If I breed a long fur ff female with a long fur ff male then what will I expect to see.... all short fur; some long fur and some short fur; all long fur
Answer:
all long fur
Explanation:
because none of them have short fur so they cant give short fur to the "baby pets"
Answer:
All long fur
Explanation:
You should expect a long fur because of the genes being passed down. Both the parents had the long fur gene so they can't give a short fur gene if they don't have it. For example if your mom had brown hair and your dad had brown hair there is no way for you to get blonde hair.
the graph represents changes to a population of rabbits after they were introduced by humans only once to a small island in a lake. describe how the changes to the rabbit population during its first two years on the island were a result of relationships between births, deaths, emigration, and immigration.
Answer: Rabbits population grows quickly after humans introduced them to the island
Explanation:at the begining, there are no Rabbits on the island so there is no intraspecific competition. Then the rabbit population grows faster because birth rate is greater than death rate and there are a lot of resources available for individuals to survive, that prevents rabbits from emigration.
The changes in the rabbit population in the first two years on the island were primarily determined by the balance between birth and death rates. Initially, the birth rate surpassed death rate leading to population growth. However, as resources became limited, the death rate increased, causing the population growth to slow and then plateau.
Explanation:In the first two years after rabbits were introduced to the island, the population dynamics were determined by four factors: births, deaths, emigration, and immigration. As an isolated island, the last two factors, emigration and immigration, are essentially non-existent as the rabbits have no means to leave or enter the island. Hence, the changes in population would primarily be driven by the birth and death rates.
Initially, the population would increase due to the birth rate surpassing the death rate — each rabbit pair can produce several litters in a year — thus leading to rapid population growth. However, as the rabbit population increases, resources like food and shelter start becoming scarce, leading to competition. This competition, coupled with predation and diseases, increases the death rate. Hence, after a period of rapid growth, the population growth slows down and then plateaus once the birth rate equals the death rate, resulting in a stable population.

Chromosomes control cell processes. They do this by?
Answer:
coding for the production of all a cell's proteins
Explanation:
Answer:
Coding for the production of all cells protein
Explanation:
Chromosomes are long sequences of DNA that contain several genes and other sequences of nucleotides. In eukaryotic organisms, chromosomes are linear structures of highly stranded double-stranded DNA, normally found in the nucleus of cells, and may also be associated with proteins and RNA. In prokaryotic organisms, they have a circular or linear shape, not being present in the nucleus or associated with proteins.
In addition, chromosomes are the molecules responsible for controlling cellular processes. They do this by coding the production of all proteins in a cell.

If net photosynthesis is 15mm/10min and cellular respiration is 1.5/10min, how much is gross photosynthesis?
Answer:
16.5 mm/10min
Explanation:
Net photosynthesis is the amount of photosynthesis left when the amount of respiration is removed from the total amount of photosynthesis (gross photosynthesis).
In other word;
Net photosynthesis = Gross photosynthesis - respiration.
Making gross photosynthesis the subject of the formula;
Gross photosynthesis = net photosynthesis + respiration
Hence, if net photosynthesis = 15 mm/10min and cellular respiration = 1.5/10min
Gross photosynthesis = 15 + 1.5
= 16.5 mm/10min
The gross photosynthesis is 16.5 mm/10min.

What is an ecosystem?An ecosystem, also known as an ecological system, is made up of all the organisms and the physical setting in which they live.
The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue. Animals play a significant part in the transfer of materials and energy through the system by eating plants and one another. They also have an impact on the biomass levels of the microbial and plant communities.
In addition to facilitating nutrient cycling by transforming nutrients held in dead biomass back into a form that can be easily utilised by plants and microorganisms, decomposers also release carbon into the atmosphere through the breakdown of dead organic matter.

in what parts of the cycle do you think carbon spends the least time?
Answer: Carbon spends the least amount of time in living things and the atmosphere.
In the carbon cycle, carbon spends the least time in the atmosphere and bodies of living organisms. It spends longer in reservoirs like soil, ocean sediments, and land sediments including fossil fuels. Human activities are altering the carbon cycle.
Explanation:In the carbon cycle, carbon tends to spend the least amount of time in the atmosphere and bodies of living organisms, where the exchange of carbon is more rapid compared to the slower geological processes. This difference in speed is primarily due to the biological processes such as photosynthesis, respiration, and decomposition that continuously move carbon through the biosphere. Carbon spends longer periods in carbon reservoirs such as ocean sediment, soil, land sediments (including fossil fuels), and the Earth's interior where geological processes dominate the cycle.
For example, plant photosynthesis removes carbon dioxide from the atmosphere quickly but this carbon can accumulate over centuries in thick forest soils. On the other side, marine organisms incorporate carbon into their bodies and upon death, they sink to the bottom of the ocean where over millions of years, geological processes convert their remains into carbon reservoirs such as fossil fuels.
Human activities like burning fossil fuels are releasing this 'stored' carbon back into the atmosphere at a rapid pace, drastically altering the normal pace of the carbon cycle and contributing to global climate change.
