Answer:
Stem
Explanation:
Stem is considered to be one of the most important part of the whole plant when it comes to giving support to the other growing parts like flowers, fruits and leaves. There are inter-nodes and nodes present on the surface of stems. nodes are the points where inflorescence, other stems and more leaves are originated.They contain important transporting tissues Xylem and phloem inside that are involved in the transport of food and minerals to the growing parts of the plants.Stem also store nutrients in the form of sugars that can later be used for the growth and development of plant as well as for the production of more tissues.Though stems are above ground part of the plant but in some plants they can be underground too such as potatoes and ginger. However, underground stems also serve same role by supporting the overall structure of the plant.Hope it help!

A) The stomach
B) The bloodstream
C) The mouth
D) The pancreas
Answer:
B) The bloodstream
Explanation:
The endocrine system releases hormones into the bloodstream. Option B is correct.
The endocrine system is a collection of glands that produce hormones, which are chemical messengers that travel through the bloodstream to target cells in other parts of the body. The endocrine system releases hormones directly into the bloodstream, where they can be carried to all parts of the body. The stomach, mouth, and pancreas are all organs that are part of the digestive system, but they do not release hormones.
Endocrine glands are glands that produce hormones, which are chemical messengers that travel through the bloodstream to target cells in other parts of the body. The stomach, mouth, and pancreas are exocrine glands, which means they produce substances that are released into ducts that lead to the outside of the body. Option B is correct.

Harold makes a very diagram to help him compare and contrast mitosis and meiosis
A. Forms diploid cells
B.creates an even number of cells
C.includes two rounds of cell division
D. Duplicates body cells
Answer:- Option C - Includes two rounds of cell division.
Explanation :-
A Venn diagram is used to depict all possible relations between different sets.In the given venn diagram-
1. The region X will consist of the features that are unique in mitosis.
2. Region Z will consist of features unique to meiosis
3. Region Y consists of features that are common to both mitosis and meiosis.
Meiosis is a process in which a cell undergoes 2 rounds of cell division known as meiosis I and meiosis II to produce 4 cells from a single cell.As a result of meiosis a diploid cell (2n) divides to form 4 haploid (n) cells. Such type of cell division is known as reductional division since, there is reduction in the number of chromosomes.The process of meiosis takes place to produce the gametes that is the sperm and the ovum.Mitosis is a type of cell division in which a single cell goes under a single round of cell division and divides to produce 2 cells.In mitosis a diploid cell thus, gives rise to 2 diploid cells.Mitosis is called equivalent division as there is no change in the number of chromosomes. The process of mitosis takes place to give rise to the cells of the body.Thus, we can conclude that both mitosis and meiosis result in even number of cells that is 2 and 4 respectively.
Mitosis is responsible for duplicating body cells and forming diploid cells.
Meiosis includes two rounds of cell division.

which type of tropism aids plants the most in photosynthesis
Tropism is the response of an organism towards any stimuli. stimuli may be light, gravity, temperature etc. In photosynthesis plants are responded towards light, and growth of their shoot system are towards the light source. This type of tropism is called phototropism.
Answer:
Tropism refers to the response a body system of the organism produces according to an external stimulus. Plants shows tropism depending upon the type of stimuli. The stimuli can be sunlight, gravity, water or even touch. The tropism related with the sunlight is phototropism. Phototropism is a typical response of a plant shoot towards the sunlight. The plant shoots grow in the direction of sunlight, hence they show positive phototropism, whereas plant roots grow in direction against the sunlight, they show negative phototropism. Phototropism helps in availing sunlight to plants which is a necessary ingredient required for photosynthesis.

Maxwell shoots a rubber band at his friend Jimmy. Which type of energy is converted into kinetic energy?
A.) Elastic potential energy
B.) Nuclear potential energy
C.) Chemical potential energy
D.) Gravitational potential energy
Final answer:
The energy converted into kinetic energy when Maxwell shoots a rubber band is elastic potential energy.
Explanation:
When Maxwell shoots a rubber band at his friend Jimmy, the type of energy that is converted into kinetic energy is A.) Elastic potential energy. This is because the rubber band, when stretched, stores energy due to its elasticity. Upon release, this stored elastic potential energy is converted into the kinetic energy of the motion as the rubber band flies towards Jimmy. This conversion is in accordance with the conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.

when the process of mitosis is correctly completed, the daughter cells should contain exact copies of all of on organisms genes. which biomolecule contains all of the organisms genes
The biomolecule that contains all of an organism’s genes is DNA. During the mitosis process, the genomic DNA is replicated, ensuring each daughter cell contains an exact copy of the organism's genes. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells, which are genetically identical to the parent cell.
Explanation:The biomolecule that contains all of an organism’s genes is DNA (Deoxyribonucleic Acid). During the process of mitosis, the genomic DNA is replicated and then allocated into the daughter cells.
This ensures that each new cell contains an exact copy of the genetic material, preserving the organism's complete genetic makeup in each individual cell. Just as you pointed out, when mitosis is correctly completed, the daughter cells should contain exact copies of all of an organism's genes.
In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells, which are genetically identical to the parent cell. This is known as cellular cloning. In bacterial cells, an analogous simpler process called binary fission occurs, where the single, circular DNA chromosome of the bacteria is replicated and passed onto the offspring cells, achieving the same outcome of identical genetic information.

A trait like eye colour or height These are equally likely to occur in male and femaleInvolves a dominant and recessive allelePredisposition to some diseases, like diabetes and heart diseasesExplanation:
Sex linked trait are those traits whose inheritance is based on the sex of individuals. The genes are usually located on the sex determining chromosomes as opposed to non-sex determining chromosomes or autosomes.
The frequency of occurrence of sex linked trait is more in a particular sex than the other. For example, baldness is more often found in men than in women, hence, baldness can be said to be sex linked. Other examples include hemophlia, color-blindness, etc.
Mendelian trait on the other hand are traits whose genes are located on autosomes. They inheritance usually follow simple dominance/recessive style and are equally likely to occur in male and female. Examples include hair colour, height, and diseases such as diabetes, etc.

what does traits will only be expressed if both recessive allies are passed down from each parent otherwise I'll be hidden in dominant allele what does that mean
Recessive Inheritance
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (ss) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the genotypes of the parents must be considered. If one parent is heterozygous (Ss) and the other is homozygous recessive (ss), then half of their offspring will have a smooth chin. In other words, any of the offspring will have a fifty percent chance of having a smooth chin. A Punnett square can be used to determine all possible genotypic combinations in the parents.
