Answer:
Responding or dependent variable
Explanation:
Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)

What are 3 things that should be kept constant in a experiment?
Answer:
There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the "constant" variable, which must remain consistent and unchanging throughout the experiment.
Explanation:
Answer:
Controlled or Constant variable
Explanation:
It does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.

HOMOLOGOUS CHROMOSOMES SEPERATE FROM EACH OTHER WHAT STAGE
Answer:
Homologous chromosomes separate from each other during anaphase I of meiosis.
Explanation:
Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.
During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.
In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.

A dependent variable is the variable that changes as a result of the independent variable manipulation. Dependent variables are also called as response variables.
A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. The independent variable in a research study or experiment is what the researcher is changing in the study or experiment.

Advantages of seed development
Answer:
The advantages of seed development include increased crop yields, improved disease resistance, and enhanced nutritional content.
Seed development in plants provides several advantages, including protection and dispersal of offspring, dormancy for survival in unfavorable conditions, and a nutrient-rich food source for germination and early growth.
Seed development in plants offers various advantages that contribute to their reproductive success and survival.
One key advantage is the protection and dispersal of offspring. Seeds are enclosed within a protective seed coat, which shields the embryo from external threats such as desiccation, mechanical damage, and predation. Additionally, seeds have adaptations for dispersal, allowing them to spread over a wider range and colonize new habitats.Another advantage is dormancy. Seeds can enter a state of dormancy, remaining inactive until conditions become favorable for germination and growth.This allows plants to survive through periods of unfavorable environmental conditions such as drought, extreme temperatures, or lack of sunlight. Dormancy also enables seeds to delay germination until suitable resources and conditions for growth are available.
Furthermore, seeds serve as a nutrient-rich food source for the developing embryo. They contain stored reserves of carbohydrates, proteins, and lipids that provide energy and nutrients for germination and early growth when the seedling is not yet photosynthetically active.In summary, seed development in plants provides advantages such as protection and dispersal of offspring, dormancy for survival during unfavorable conditions, and a nutrient supply for early growth and development. These traits contribute to the reproductive success and resilience of plants in diverse environments.

What feature about water gives it such unique properties?
Its polarity and bond angle
Water being made up of oxygen and hydrogen
Water being able to dissolve substances
Water being in all cells
Its polarity and bond angle makes water unique properties.
The structure of water molecules is twisted and polar, with partial positive charges on the hydrogens and partial negative charges on the oxygen. This is because oxygen attracts electrons more effectively than hydrogen since it is more electronegative. A great solvent is a water.
Cohesion in water is caused by its polarity. The forces that induce or permit similar molecules to stick together are referred to as cohesion. Water has cohesiveness because its molecules naturally desire to adhere to one another.
When water is not boiling into a gas or freezing into a solid, it is in a liquid condition. When it is liquid, water has the lowest density.
