Answer:
B. A plant cell has a well defined shape because it has a cell wall
Explanation:
When you compare an animal cell to a plant cell you can see that a plant cell has a cell wall while and animal cell only has a cell memebrane. The cell walls of the plant help the plant by providing support and keeping it's shape.
The difference between plant and animal cells is plant cell has a well defined shape, because it has a cell wall.
What are the functions of cell wall?The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants.
The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides.

Parent strand of DNA is CCTAGCT. What is the complementary strand?
Answer:
GGATCGA
Explanation:
Adenine goes with thymine and Cytosine e goes with guanine.
Basically A is with T; C is with G
Note that:
C matches with G
T matches with A
In this case, the strand of DNA given is CCTAGCT. The complementary strand would therefore be GGATCGA.

3. Suppose two animals live in the same loca-
tion and eat the same kind of food. What
adaptation would decrease the competition
between them?
Answer:
One eats during the day and the other eats at night.
Explanation:
Answer:
Well, it really depends on the type of animal (for example water, land). However an adaptation like being able to eat different foods would decrease competition between them as they don't have to hunt the same prey.
Explanation:
I don't really know how to explain this. Sorry if my answer is bad.
The mitochondria of eukaryotic cells contain two forms of the EF G protein. EF G1mt acts an elongation factor as expected, but EF G2mt acts as a ribosome recycling factor. Individuals with certain single nucleotide polymorphisms (SNPs) in the EF G2mt gene are known to have an increased number of side effects associated with taking statin drugs that treat high cholesterol. The most common side effect is muscle weakness, but they can be as severe as muscle breakdown and liver failure. Propose a mechanism by which SNPs in the EF G2mt gene may lead to these side effects.
Answer:
The correct answer is - polymorphism mechanism.
Explanation:
Polymorphism mechanism in mitochondrial elongation factor gene EFG2: It involves escalates the atorvastatin toxicity and affects the cell respiratory function. Polymorphisms within the EFG2 factor gene lead to the implication in disease. This gene factor may result in adverse drug reactions such as STATIN, that can leads to side effect to the condition that can affect skeletal muscle severely.
EFG2 plays an essential role which is specific in mitochondrial ribosome recycling. EFG2mt gene is required for cell growth on galactose medium using small interfering RNA splicing of expression in human cell lines.
Such mutation exhibits an atorvastatin-sensitive phenotype and shows less respiratory capacity. this concludes that the first phenotype associated with SNPs in the EFG2mt gene and implicates the human EFG2mt gene as a pharmacogenetic gene for stain toxicity in humans.

The honeybee has 32 chromosomes in their somatic cells. They undergo meiosis but can
produce offspring drones without fertilization. How many chromosomes does the drone have?
What does this mean for the drone?
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.

What challenges do researchers trying to breed fungus-resistant Cavendish bananas face?
The two diseases currently attacking banana crops around the world are known as Black Sigatoka and Panama disease. Both are caused by fungi species which grow inside banana organs, draining away their nutrients or reducing their ability to photosynthesise. These fungal parasites slowly starve the banana to death.

Okazaki fragments are formed on which strand?
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.

What are the 2 laws Mendel came up with?
Mendel's Laws of Heredity are usually stated as: 1) The Law of Segregation: Each inherited trait is defined by a gene pair. ... 2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
RNA differs from DNA in that RNA has?
A. a double strand and contains uracil.
B. a single strand and contains adenine.
C. a single strand and contains uracil.
Answer:
C. a single strand and contains uracil.
Explanation:
DNA has 4 bases: adenine, cytosine, guanine, and thymine and is double stranded while RNA is one stranded and instead of thymine, it uses uracil.

Which of the following explains the role of plants in the carbon cycle?*
(1 Point)
Plants transfer oxygen and carbohydrates in the biosphere to carbon dioxide in the atmosphere.
Plants transport carbon dioxide in the atmosphere to groundwater.
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Plants transfer oxygen in the atmosphere to fossil fuels.
Answer:
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Explanation:
Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.
However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).

List two general differences between inner and outer planets.
Astronomy.
Answer:
Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.
Explanation:
The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal.
The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.
The outer planets are made of hydrogen and helium, so they are called gas giants.
