Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?

Answer:

C

Explanation:

Everything else has to do with growth but C is talking about food/energy.

A plant using sunlight to make its own foods is accomplished by repeated cell division.

Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

A. because mitiosis creates a cell that is exactly the same as it's parent. It's kinda like having a parent/grandparent that looks just like you

Answer:

Herbivorous animals are unable to feed and end up migrating to other regions in search of food.

Explanation:

The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.

The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.

Explanation:

The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .

When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

A & O group

Explanation:

Dad will be having io io allele and mom will be having ia io

The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.

A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).

A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.

Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).

The child will have blood type O if both parents carry the O allele (genotype OO).

Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

The structure shown by the red arrow is cell membrane.  

In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:  

1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.  

2. It prevents toxic components from entering the cell.  

3. They distinguish essential but incompatible metabolic procedures conducted within the cell.  

Explanation:

The function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).

Answer:

movement of chemicals into the dendrites of the neuron

Explanation:

Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.

Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.

An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

the organs that are directly involved            the organs which helps the  

in digestion like stomach,  small intestine,      digestive organs by thier  

large intestine etc                                             scretions or by other means like

                                                                         liver ,pancreas etc

2.  food                              bolts                            chyme

                                  DIFFERENCES

the substance which    The semi hard       the soup like substance

is eaten by a person.   substance  

it is semi digested in    it leaves oral cavity    it leaves stomach and went to

oral cavity.                   and move to stomach                small intestine        

                                     SIMILARITIES

They all are nutrients containing meterials which are to be digested. they all contain carbohydrates,protiens ,fats and vitamins (somehow if the food is taken from plant source) and they all are about to be absorbed.

3.DIGESTIVE SYSTEM:

            the process in which food substance is broken into pieces and is converted into the simpler substances which can be assimilate by body cells. Different glands scretes digestive juices which digest fats,protiens ,carbohydrates etc e.g gastrin,bile,pancreatic juice and intestinal juice. and at the end all the product remain is excreted out after assimilation.

ORGANS INVOLVED: oral cavity,oesophagous,stomach small intestine ,large intestine.

4.  salivary glands are damaged:

      if salivary glands are destroyed or damaged then no saliva will produce to protect the walls of gut and the gut walls will be damaged by the acidic or basic juices of gut which will causes severe ulcer of oesophagous, stomach or intestinal.

5.CONSTIPATION:

     when too much water is absorbed by the walls of large intestine so the end product which is to be excreted will become so hard that it is dificult to excrete 0it out of body.

  CAUSES: it may be caused by hormonal disturbance ,water deficiency and may be by silliness of a person that he use to be silly to go to the bathroom at time.

6. INGESTION: Taking of food from the outside of the body from different means which contain nutrients essential for body growth.

DIGESTION: Breakdown of food into simpler substance  which can be easily taken by body cells .

ABSORPTION:Large intestine and smaal intestine absorbs the certain amount of nutrients and water from the digested substance to fullfil the body deficiencies. These nutrients are then assimilated into the body.

EXCETION:the substance which remain after absorption is excreted out of the body from exterior opening called anus is called excretion.

The growth of the algae came from the air and water in the bottle.

The statement (D) is correct. The growth of the algae came from the air and water in the bottle.

Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.

Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

Answer:

Adaptations are inherited traits that increase an organism's chance of survival, also determine an organism’s niche.

Explanation:

Adaptations can be defined as inherited traits that increase an organism's chance of survival and determine its niche. An organism's niche is the place it has in an ecosystem it inhabits - how it lives and survives in it and how it affects it and other species.

Adaptations are a necessary occurrence. As the organism's habitat changes, it has to change as well. In order words, it has to adapt. This process is supported by natural selection - the mechanism that ensures that an advantageous characteristic will become the most common one.

An example of adaptation is what an animal's teeth look like. The shape of an animal's teeth heavily depends on its diet. If it's a herbivore, it will have many molars for chewing grass and plants, and if it's a carnivore, it will have sharp canines to help it tear meat.
