Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

The cells of the leaf of the grape plant are able to make sugars which are then transported to the grapes. Describe the process by which sugars are made in a leaf cell.
Answer:
yes
Explanation:
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen

Answer:
Explanation:
Skeletal Adaptations. Giraffes, lizards, and many other known species adapted to their environments through genetic changes to their skeletons. Coloration. Many species have been studied who've adapted to their environment through adaptions in coloring. Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds. However, natural selection does not always go to the optimum. An example of variation is that I have a cat with black fur and one with yellow fur. Trait that can be PASSED DOWN to offspring through genes. Inherited characteristic that INCREASES an organism's chance of survival or reproduction in its environment.
Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell
membrane, because is it semi-permeable, allowing small molecules to cross the membrane, but NOT larger molecules, like starch
A starch solution is placed in the dialysis tubing and then the dialysis tubing is placed in an iodine and water solution. lodine is
used as an indicator for the presence of starch. Normally, iodine is a yellow-brown color, but in the presence of starch, it turns a
deep purple. After observing the experimental setup for 20 minutes, the iodine solution remains brown, but the starch solution
inside the dialysis tubing is purple and swollen. Based on what you learned from the lab, starch is MOST likely to cross the cell
membrane at which of the points indicated on the diagram?
ah
ing
Starch requires ATP energy for transport and therefore cannot cross the dialysis tubing into the iodine solution.

Air masses always move in which direction?
Answer:
They move with the global pattern of winds.
Explanation:
Answer:
They move with the global pattern of winds. In most of the United States, air masses generally move from west to east. They may move along with the jet stream in more complex and changing patterns. When an air mass moves to a new region, it carries along its characteristic moisture and temperature.

Gene therapy is a form of _____
Selective breeding
Artificial selection
Cloning
Genetic engineering
Answer:
Genetic engineering
Explanation:
Genetic engineering involves a process of using recombinant DNA technology to change the genetic make up of an organism.
This is done in order to address certain issues or to boost food production
Gene therapy is a form of genetic engineering. In this process, bad genes that causes certain diseases are replaced with healthier ones. Selective breeding, artificial selection and cloning are other forms of genetic engineering.Answer:

(-107)-(-97)+(-10)
Answer: -20
Explanation:
Here is the equation to solve:
(-107)-(-97)+(-10)
First and foremost, we should note that:
- × - = +
- × + = -
Therefore, (-107)-(-97)+(-10)
= -107 + 97 - 10
= 97 - 107 - 10
= 97 - 117
= -20

What is one job proteins do NOT have in the body
1.serve as a layer of insulation
2.support the immune system
3.structure for tissues and organs
4.serve as enzymes
Answer:
1. serve as a layer of insulation
is not a job of proteins
Proteins do not serve as a layer of insulation in the body.
WHAT ARE PROTEINS:
Proteins are one of the four biomolecules in living organisms. Proteins are made up of long chains of amino acids linked together by peptide bonds.
FUNCTIONS OF PROTEINS:
Proteins in the body are synthesized to perform varying functions. These functions include:
Enzymes: Proteins are the major components of enzymes responsible for regulating series of biochemical reactions in the body. Structure for tissues and organs: Proteins make up the structural components of many tissues and organs in the body. For example, keratin is a protein found on the skin. Support the immune system: Proteins provide support for the defense system of the body.Therefore, among the many roles that protein play in the body, serving as a layer of insulation is not one of them. It is rather the function of LIPIDS.

What could happen to the foxes if the grasshoppers disappear? WHY?
If a certain organism is a primary consumer, what best explains its position in the food web? (See picture above)
A. X, because organism X has the same role as the grasshopper
B. y, because organism Y has the same role as grasshopper
C. x, because organism X has the same role as the baby sparrow
D. Y, because organism Y has the same role as the baby sparrow
Answer:
A. X, because organism X has the same role as the grasshopper
Explanation:
In the food web the organism is denoted by X and it shares the same role as the grasshopper.
A primary consumer is mostly a herbivore. They feed directly on plant matter and convert them into useful nutrition for their own needs.
Grasshoppers feed on grasses. They are able to process plant matter into digestible food materials.Organisms of this kind are primary consumers. Organism such as Y are the secondary consumers. They feed on other organism but not directly on the plants.Answer:
A : X, because organism X has the same role as the grasshopper
