A. General Cell Processes
B. Growth
C. DNA Replication
D. Mitosis
Answer:
A. General Cell Processes
B. Growth
C. DNA Replication
Explanation:
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. So, the option A, B and C are correct.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Choose the combination of factors that creates snow.
Answer:
Relative Humidity- Low
Air tempurature-cold
Air Pressure-low
Explanation:
High pressure, warm temperatures, and high humidity are factors that creates snow.
What are the factors that create snow?Snow and/or ice formation requires temperatures below freezing, both in the atmosphere and close to the ground.
Something that will induce the moist air to rise, forming clouds and precipitation, moisture, produces precipitation and clouds.
Water that has frozen solidly is snow, and the atmosphere (layer of gases around Earth) contains water in the form of vapor (gas). When there is a lot of vapor present, clouds develop, fill up with water droplets, and eventually begin to rain.
Therefore, when a very cold water droplet freezes onto a pollen or dust particle in the atmosphere, a snowflake starts to form.

The ___ of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The ___ of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, ____ either break or form.
Thus, water absorbs or releases a great deal of ____, helping to moderate temperatures.
Water is a versatile ____.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved ______.
Answer:
The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, hydrogen bonds either break or form.
Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.
Water is a versatile solvent.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.
Explanation:
The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.
Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.
Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.
The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.

Answer:
The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,
Explanation:
It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.
Answer:
(Q1) Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
(Answer)They are vestigial structures that once performed an important function for human ancestors.
(Q2) Which statement is true?
(Answer) Imprints of leaves or footprints in sedimentary rock are fossils.
(Q3) Which statement about these fossils is supported by the evidence in the diagram?
(Answer) Homo erectus is the most recent ancestor to modern humans.
(Q4) Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
(Answer) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
(Q5) Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?

what is the part of endoplasmic reticulum without proteins attached?
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.
Farmer toon soon wanted to start breeding his plants so that they are resistant to disease while producing more fruit per plant.Which plants should the farmers cross to get the desired (wanted) combination of traits
Answer:
cultivated plant variety with its wild type variety.
Explanation:
The farmer cross the cultivated plant variety to its wild type which has the characteristics of resistance against diseases. Due to crossing, the offspring produce having resistance against that disease as well as producing high yield. This type of crossing is known as artificial selection in which humans cross two organisms to get the desired characteristics in their offspring so to get a plant with resistance against disease we cross cultivated plant variety to its wild type.

What characteristics of the blood cell helps it to pass freely through blood capillaries
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.
Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?
Answer:
The correct answer is - Disruptive selection.
Explanation:
Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.
In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.
