Answer:
The difference between the given terms is summarized below.
Explanation:
Pollen cells:
Single or perhaps even more vegetative cell lines as well as a reproductive cell come in the form of pollen. The masculine gamete is not a pollen crop on its own.Algae cells:
There will only be a singular nucleus throughout many of these algal cells, whereas other cells have become multi-nucleate. Furthermore, several other algae were indeed saponaceous, which means that cell walls aren't differentiated from one of the several nuclei.The differentiation between pollen cells and algae cells can be seen from the habitat in which they thrive and their structural characteristics.
The pollen cells are reproductive structures in a plant that gives rise to the male gametophyte that houses the male reproductive cell of a plant. During pollination, they are being transferred to the stigma by to the presence of spikes around the pollen cells which attaches to the bees (an agent of pollination).
The algae cells are single or multinucleate eukaryotic cells, that live in swampy and wet habitats. The presence of the tail in the cells helps in the locomotion of the cells to the area where their fertilization takes place.

Answer: the answer is C
Explanation: mutation is a change in dna that results in overall structure changes to organisms
A spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.
In genetics, a spontaneous and unpredictable variation in the sequence of genes that make up the DNA of a living being that introduces specific changes is called a mutation.
This alteration, which can be hereditary, implies a modification of its characteristics.
These types of changes occur spontaneously and naturally, product of errors in the replication of the genome during the phases of cell replication.
From a mutation, the living being can develop different diseases, manifest changes in its organism or hereditary defects.
Despite of this, mutations are key to sustaining high genetic variability, promoting adaptation and evolution (even creating new species in the long run).
Therefore, we can conclude that a spontaneous change in DNA that may lead to cellular malfunction is the most complete and accurate description of mutation.

All genes are made of DNA genes code for proteins proteins carry out life functions
O All genes are made of proteins, proteins code for DNA DNA carries out life functions
As
Answer:
Genes are made of DNA; DNA codes for proteins; proteins carry out life functions
Explanation:
The correct statement is "All DNA is made of genes: DNA codes for proteins: proteins carry out life functions"
The deoxyribonucleic acid (DNA) chain is known as a gene, a structure that is constituted as a functional unit in charge of the transfer of hereditary traits.DNA is the biopolymer that houses the data for the synthesis of proteins and that makes up the genetic material that cells have.The functions of proteins are specific to each of them and allow cells to maintain their integrity, defend themselves from external agents, repair damage, control and regulate functions, among other life functions.Therefore, we can conclude that DNA stores the instructions for the synthesis of all the proteins that make up an organism and the minimum units of this genetic information are called genes.

ATP
sugar
carbon dioxide
water
Answer:
It starts with sugar, or C6H12O6 being broken down.
Explanation:
Also, as seeing that it is the only macromolecule here and because of the fact that glycolysis uses glucose, or sugar, your answer is B, sugar.
The macromolecule that provides the energy that starts glycolysis is ATP.
ATP:
Adenosine triphosphate (ATP) is a biological molecule that stores and releases energy for living cells.ATP is structurally adapted to its function. It releases energy for use by most metabolic activities that occurs in living cells.One of these metabolic activities is glycolysis, which is the process by which glucose sugar is broken down in the cytoplasm of the cell. Glycolysis is the first stage of cellular respiration and it requires 2 molecules of ATP to occur.

Which zoologist stated that all animals are composed of cells
Answer:
Theodor Schwann
Explanation:
A test cross to determine the genotype of a green-colored seed would best be represented by _______.
a. Yy x Yy
b. YY x YY
c. YY x Yy
d. Yy x yy
Answer:
d. Yy x yy
Explanation:
In Mendelian inheritance, a TEST CROSS is a cross used to determine the actual genotype of a dominant phenotype. The test cross is usually performed between the unknown genotype and a recessive genotype. If all the offsprings are dominant, the unknown genotype is the same allele but if the offsprings are half dominant and half recessive, the unknown genotype is HETEROZYGOUS.
In this case, a test cross to determine the genotype of a green-colored seed would best be represented by Yy × yy because a test cross must include a recessive genotype, which is "yy" in this case.

What would happen to a bunch of balloons that were inflated outside when it was 95 degrees F and you took them into an ice hockey rink where it was 45 degrees F *
Answer:
The balloon shrinks
Explanation:
According to Charles law, temperature and volume are directly proportional. When temperature increases, volume of the gas inside the balloon increases and vice versa at constant pressure.
However, when the balloons are taken into an ice hockey rink and their temperatures drop from 95 degrees Fahrenheit to 45 degrees Fahrenheit, the molecules of gas in the balloons loose energy and move at slower speeds tending to stick closer together. The volume of the balloon therefore decreases accordingly. This means that the balloon shrinks.

If population remain geographically isolated for thousands of generations, what would happen?
Answer: They would die, or go insane
Explanation: First off, they need to have a steady food supply to maintain society. If, lets say, the food ran out, then everyone would die as they were isolated and had no other food source. Since the human body needs to have interaction, if a certain group of people were isolated, they would most likely also go insane due to the lack of no other people. Of course, the info you gave was very vague, so I couldn't really give a good answer, so yeah
Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
A. The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.
B. The energy flow—and thus oxygen flow—for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another.
C. Cellular respiration is a process that releases energy and oxygen, while photosynthesis withdraws energy and uses oxygen, therefore keeping each process in balance.
D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen.
the answer would be A
The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. Hence option A is correct.
What is photosynthesis?Photosynthesis is defined as the process through which green plants use energy from sunlight to transform carbon dioxide and water into food. The process of photosynthesis is used by plants, algae, and some microorganisms to convert light energy into chemical energy. Photosynthesis is a process, not an event. Every time sunshine is present, it happens continually.
Specifically, glucose-stored energy is converted to ATP during cellular respiration. The chemical energy the cell can use is called ATP, or adenosine triphosphate. It is the molecule that gives your cells the power they need to carry out tasks like contracting your muscles when you walk down the street.
Thus, the net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. Hence option A is correct.

Why do you think it is important for a cell to grow before it replicates its DNA? Be as specific as you can in your answer
Answer:
Basically, every time a cell undergoes mitosis (one kind of cell division), various enzymes work to split each DNA strand in half, and then replace the missing half on the separated strands with corresponding nucleotides, leaving you with two identical strands. When the entirety of a cell's genome is copied (along with all the organelles), the cell can split into two daughter cells.
Imagine slicing yourself down the middle and splitting yourself in half, and then using each half of you as a template to recreate the other half.
That's the biology behind it, but the bottom line is that DNA is replicated in order to reproduce itself.
Explanation:
It is important for a cell to grow before it replicates its DNA so - each daughter cell gets the same number of identical DNA.
DNA replication needs to occur because existing cells divide to produce new cells.
Each cell needs a full instruction manual to operate properly.So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.This way each cell gets the same instructions to perform the cellular functions.Thus, it is important for a cell to grow before it replicates its DNA so - each daughter cell gets the same number of identical DNA.

Photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.
Photosynthesis refers to the series of metabolic reactions by which plants use carbon dioxide from the atmosphere and sunlight to produce oxygen and simple carbohydrates (i.e., sugars).
Conversely, cellular respiration is a series of reactions by which aerobic cells use oxygen from the atmosphere and the energy stored in the chemical bonds of foods to produce carbon dioxide and ATP.
Photosynthesis reactions can be divided into light-dependent relations and light-independent reactions.
Moreover, cellular respiration has three stages: glycolysis, the acid citric cycle and oxidative phosphorylation.
In conclusion, photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.
