Answer:
Algae
Explanation:
Along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.
Answer:
That's easy It's plant's.
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

How will the changes to the geosphere affect the atmosphere, hydrosphere, and biosphere?
Answer:
That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. ... Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth.
Explanation:
The space that includes minerals and rocks of earth surfaces found on mountains, shores and valleys are called the geosphere. It comprises abiotic factors.
The hydrosphere is the water surface of the planet and consists of oceans, seas, rivers etc. The water from the hydrosphere precipitates and forms rain that can cause soil erosion on the geosphere.The atmosphere gets affected by the geosphere as the soil component from the geosphere affects the transpiration and evaporation rate of the atmosphere.Geospheres affects the biosphere as the activity of surfaces like volcanic eruptions causes pollution in the atmosphere but the soil rich in minerals from volcanoes are good for biosphere life-like plants.Therefore, the geosphere can affect the atmosphere, hydrosphere and biosphere in good and bad ways.

When a large group of cats is introduced
to the food web illustrated, almost all of
the mice are consumed in just a few
weeks.
Which population will likely show the
largest increase as a result?
(1) insects
(2) foxes
(3) rabbits
(4) hawks
(5) Squirrels
The population that will likely show the largest increase as a result of almost all of the mice being consumed is insects.
Explanation:The population that will likely show the largest increase as a result of almost all of the mice being consumed by a large group of cats is (1) insects.
When the mice population decreases due to predation, the insect population may increase because there will be fewer mice feeding on the insects and competing for resources. This may lead to a larger availability of food and less competition for the insects, allowing their population to grow.
Additionally, the decrease in the mice population may also indirectly benefit other populations such as foxes and hawks, as they rely on mice as a food source. With fewer mice, these predators may turn to insects as an alternative food source, further contributing to the increase in the insect population.

A student wants to cross parent mice to produce offspring with black fur and offspring with white fur. If black fur color (B) is dominant to white fur (b), what should be the genotypes of the parent mice?
Answer:
Bb and Bb
Explanation:
I used a Punnett Square.
The genotype of the parent mice should be (Bb), the offspring produced from the cross between Bb and Bb parents will produce mice with black and white fur in 3:1 ratio.
What is Genotype?
Genotype is the genetic makeup of an organism. Genotype describes an organism's complete set of genes. In mice, the black fur (B) is dominant over the white fur (b).
The cross between parent mice with genotype (Bb) i.e., heterozygous black fur will produce offspring with BB (homozygous black fur), Bb (heterozygous black fur), and bb (homozygous white fur) in 3:1 ratio.

During cellular respiration, cells obtain energy for performing work when...
I. energy-rich molecules of glucose are broken down in the cytoplasm, and ATP is produced.
II. enzyme pathways in the mitochondria produce ATP through the process of fermentation.
III. enzyme pathways in the mitochondria produce ATP in a process that requires oxygen.
I, II, and III
II and III only
I and II only
I and III only
Answer:
I and III only
Explanation:
The term cell breath alludes extensively to the creation of ATP through the synthetic breakdown of glucose into carbon dioxide and water. Be that as it may, this procedure has a few segments. Your body utilizes cell breath to change over glucose to ATP and carbon dioxide utilizing oxygen. Glucose travels through three phases in cell breath, glycolysis where glucose is changed over to pyruvate, and two ATP and NADH are made.
The main part of the procedure is performed anaerobically (without oxygen) in the cytoplasm when glucose atoms are changed over to particles of pyruvic corrosive, and ATP is delivered. Pyruvic corrosive atoms at that point proceed to the citrus extract cycle where they are separated into carbon dioxide and electrons, and more ATP is delivered. Cell breath happens in both eukaryotic and prokaryotic cells, with most responses occurring in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes.
Fermentation is a separate process from cellular respiration and is therefore an incorrect answer.
A population that is isolated in a remote environment is still able to experience genetic variation How could genetic variation that contributes to evolution occur in such a population
A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.
Explanation:
The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.
Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.
It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.

is the union of an egg and sperm cell
Answer:
Fertilization is the union of an egg and sperm cell, process that occurs in sexual reproduction.
Explanation:
Fertilization or fecundation is a biological process that occurs in the context of sexual reproduction of living beings. It consists of the union of gametes, male (sperm) and female (egg), provided by the parents.
As a result of fertilization, the zygote is produced, a cell that will suffer successive divisions to form the embryo, the beginning of a new individual.
Both reproduction and fertilization are necessary processes for the perpetuation of a species.

Why must the quality and quantity of DNA in cells remain the same from generation to generation?
Explanation:
As all organisms depend on their DNA to live, and any changes in the amount or quality of DNA. It will lead to mutations or death of the organism. If DNA is changed then it will be difficult for the chromosomes to match up and offspring will not be produced. The quality must be maintained. Otherwise other system in the body will not work properly.The quality and quantity of DNA in cells remain the same from generation to generation - to produce offspring and proteins for survival.
Any kind of change either quantity or quality of DNA causes abnormality in the production of proteins or viable produce as genetic information is not as it is supposed to be.
Such changes are called mutation or chromosome abnormality.DNA quality could be changed by the nucleotides being in the wrong order or extra or fewer bases.This results in the coded instructions being wrong and faulty proteins are made or control switches being changed.The body can't function as it should.Thus, for a healthy offspring and body, the quality and quantity of DNA in cells remain the same from generation to generation

What is the function of control rods in a nuclear reactor?
make radiation
control steam
make fuel
control reaction rate
The function of control rods in nuclear reactor is to control reaction rate
Explanation:
Control rods are an essential safety system of nuclear reactors. They are employed in nuclear reactors to maintain the "fission rate of uranium or plutonium". Their structures include chemical components such as boron, cadmium, silver, or indium, that are proficient in assimilating many neutrons without themselves fissioning.They form a fundamental element of an "emergency shutdown system "(SCRAM).A control rod is separated from or included into the reactor core to expand or reduce the reactivity of the reactor (increase or decrease the neutron flux). By the variances of the reactivity the changes of neutron power are delivered. This in turn influences the thermal strength of the nuclear reactor, the volume of steam produced, and henceforth the electricity is produced.Answer:
