Explanation:
Please write about Gregor Mendel and his research with pea plants and early genetics. In your writing you will need to correctly use the following words so that their meaning is understood. Some pictures are presented if you want to use them.
●Sexual Reproduction ●Hereditary ●Traits ●Purebred ●Phenotype
● Genotype ●Dominant allele ●Recessive allele • genes • Probability
Answer:
Answer: Gregor Mendel is an Austrian monk that studied genetics and heredity. Mendel wanted to determine how traits were inherited by offspring. many believed that heredity blended together in offspring. He used pea plants for his experiment because they reproduce sexually. He used cross-pollination in order to fertilize one pea plant by using the pollen of another. For each trait he studied, all hybrid offspring had only one character from each parent. The allele that appeared in the phenotype appeared to be dominant, and the allele that only showed up in the genotype and not the phenotype. In his expiriement he concluded that different forms of a gene account for the variations in the inherited traits. An organism inherits two genes, one from each parent, the probabilty of inheriting this trait depended on if it was dominant or recesive. Some alleles dominate others for a given trait (dominant and recesive.) And Finally the genes of a given gene segregate during gamete production.

Aerobic respiration takes place in the mitochondria because?
how are the cells in the leaf of a plant and the cells in the roots of the plant different
Answer:
Explanation:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. ... Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
Answer:
genrally speaking :
1)the cells of a leaf have chloroplasts, the root cell doesnt
2)as a result of the first point, root cells dont carry out photosyntheis
3)the root hair cells have elongated structures for water and mineral absorption

Describe how gene therapy can be a social issue and give rise to moral, ethical and legal debates. Justify your response in two or more complete sentences in the essay box below.
Answer:
Gene therapy is the process or replacing mutated genes with normal genes in an attempt to heal diseases by correcting the functional code of the gene. Mutated genes can cause genetic disorders. Transformation and transfection are the two methods used to insert a normal gene into an organism. The process of transformation occurs in a laboratory. Cells are grown in the lab and then introduced to DNA that carries the gene of interest. Transfection uses a virus to introduce the gene of interest to the host cells.
Gene therapy is a relatively new biotechnology. It is very expensive and much more research needs to be done before it is perfected. Gene therapy has had the best results in the treatment of cancer. One of the ways gene therapy is used in cancer treatment is by inserting a gene that is more sensitive to treatments such as chemotherapy and radiation.tion:

what change in a population would you expect to see if a selection pressure was against the traits of the dominant allele?
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

https://brainly.com/question/18592700
Decrease occur in the population of dominant allele occurs.
Change in a population of dominant allele occurs if a selection pressure was against the traits of the dominant allele because the selection pressure is against the dominant allele that leads to appearance of recessive allele and disappearance of dominant allele. The selection pressure is responsible for the appearance of allele in the offspring so we can conclude that dominant allele is decreases in the population of the future generation.

Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.
Answer:
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.

Identify the structures of the cells and the routes by which water and minerals pass through to the vascular tissue.
Answer:
Xylem
Explanation:
Xylem is a conducting tissue found in vascular plants in which most plant use to obtain water and minerals they need through their roots. Water and mineral moves from the soil to roots to stems and to leaves. The minerals such as potassium (K+), Calcium (Ca2+) travels in dissolved for in the water with various organic molecules supplied by root cells.
Water and minerals enter the root by different paths but converge in the stele, or central vascular bundle in roots.
Water conducting cells is known as tracheary elements.

What is cellular respiration ?
A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.

A student collects a sample of water from a pond near her home. She
examines a drop of the water under a microscope and sees four very
differently shaped single-celled organisms. Which of the following
can she reasonably conclude as the reason the organisms look so
different?
Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so
