Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is

Answers

Answer 1

Answer:

The movement of water from an area of high water concentration to an area of low water concentration is known as osmosis. Diffusion is also one such mechanism in which particles move from high concentration to low concentration. But, there is a difference between diffusion and osmosis. In osmosis, the movement occurs through a semi-permeable membrane. In cells, plasma membrane acts as semi-permeable membrane. Osmosis is a very important phenomenon to sustain life in biological systems because it helps in maintaining homeostasis. Homeostasis on the other hand is a process which aids living beings in regulating their daily activities so as to maintain stable internal environment. For example, if a cell becomes dehydrated (flaccid cell), then it can be easily rehydrated by keeping it in an environment full of water i.e. a hypertonic solution . The water will enter into the cell by osmosis thereby making it rehydrated again.

Answer 2

Answer: The movement of water from an area of high concentration to an area of low concentration is osmosis, I believe.

When Mendel crossed true-breeding pea plants that have inflated pods (PP) with those that have constricted pods (pp), it was observed that F1 offspring had a genotype of Pp. What would their phenotype be?

Answers

So the question is all about breeding two inflated pods. So the best answer would be this one:
F1 has Pp genotype. It is heterozygous. If you have a dominant allele, you will get the 'dominant' phenotype no matter what you have on the other allele. Usually people use upper case letter as dominant allele and lower case letter as recessive allele. So, in this case P is inflated and p is constricted. The F1 phenotype is inflated pods.

Explain why animals have specialized excretory organs but plants do not. ...?

Answers

They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

which of the following hormones has a different effect when it is released in males instead of females?

Answers

Answer;

Follicle- stimulating hormone (FSH)

Explanation;

-Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or insufficiency of it can cause infertility or sub-fertility both in men and women.

-Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes.

-In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production.

Human sex characteristics and biological-oriented behaviors are sometimes the cause of the hormonal release inside the gland organs in the human body. For instance, in males testosterone is the hormone or gland which is responsible for the many functions of the male sex characteristics.
