Q. How is the sex of the child determined in human beings ?
Please answer dis also..thanks!
➜ In human beings, sex of the child depends upon which kind of male gamete fertilise the female gamete. If sperm carrying X chromosome fertilises the ovum carrying X chromosome, then the child born will be a girl. If a sperm carrying Y chromosome fertilises the ovum which carries X chromosome, then the child born will be a boy.

Explanation:
1. maybe there aren't enough local stores in your area and you have to walk or drive miles just to get there, 2. maybe you have some connotation with people around you, or they themselves are setting good examples for you or your family, the community is too crowded, 3.maybe you want to leave a country because the system doesn't work for you, discrimination laws or a form of unfairness and mistreatment. maybe too intrusive.
Answer:
Explanation:
There are five types of isolation that biologically prevent species that might otherwise interbreed to produce hybrid offspring. These are ecological, temporal, behavioral, mechanical/chemical and geographical.May

Answer:
Explanation:
Cytoplasmic organelles are "little organs" that are suspended in the cytoplasm of the cell. Each type of organelle has a definite structure and a specific role in the function of the cell.
One of the major concerns about seawater desalination is its high expense. Another concern is the disposal of leftover brine from the desalination process back into the ocean, which harms marine life. Discuss whether these two concerns are enough to prohibit the widespread use of desalination as a source of drinking water.
Answer:
Yes.
Explanation:
Yes, these two concerns are enough to prohibit the use of desalination as a source of drinking water because this method is too expensive as well as bad for the marine environment. First, this desalination process is too expensive which is non-economical for the country while on the other hand, it greatly damaged the aquatic animals so this method must be stopped due to its adverse effect on both economics as well as environment.

The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.
What are dihybrid crosses?They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.
In this case, the two traits follow the Mendelian pattern and thus, assort independently.
Hence, the traits and their respective ratios would be:
Brown body, Red eyes - 9/16
Brown body, brown eyes - 3/16
Black body, red eyes - 3/16
Brown body, brown eyes - 1/16

How does pregnancy begin?
A. A placenta forms in the uterus.
B. Contractions begin in the uterine wall.
C. A sperm reaches an egg in the fallopian tube.
D. The blastocyst differentiates into two cell types.
Pregnancy begins with reaching of sperm to an egg in the fallopian tube. The correct option is C.
What is fertilization?Fertilization is outlined as the merger of two haploid gametes, the spermatozoa and the oocyte.
It happens for the establishment a zygote and initiate a sequence of mitotic divisions that consequences in cell differentiation and embryo progression.
Fertilization is the starting point of pregnancy.
Thus, the correct option is C.

Based on the information given, state ONE way the bag or its contents will have changed by the next day. Support your answer with an explanation. *
Answer:
The size of the bag will shrink due to movement of water molecules out of the bag into the beakerdue to osmosis.
Explanation:
The difference in concentration between two regions results in a phenomenon known as diffusion.
Diffusionnis the process by which molecules of a substance move from regions of higher concentration to regions of lower concentration until equilibrium concentration is reached by the two regions. Water molecules moves across regions of different concentration through a semipermeable membrane in a special form of diffusion known as osmosis.
Osmosis refers to the movement of water molecules from regions of high concentration (dilute solutions ) to regions of low concentration (concentrated solutions ) through a semipermeable membrane until equilibrium is attained.
The solution in the bag is less concentrated than the solution innthe beaker. The bag serves as a semipermeable membrane allowing water molecules to move out of it into the beaker due to the difference in concentration of the two solutions. As a result, the size of the bag shrinks while the level of the solution in the beaker rises as it becomes less concentrated.

C. It would not be able to store energy or communicate with other cells
D. It would not be able to store water or protect itself from viruses

(D) It would not be able to store water or protect itself from viruses
Explanation:
Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.
In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.
How will photosynthesis and respiration keep you alive, and what do you need to do?
Explanation:
While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. (hopefully this helps)
