Living things are mostly made up of four elements: carbon, hydrogen, nitrogen, and oxygen. Describe how plants and animals obtain these elements.
Answers
Answer:
Explanation:
Animals obtain carbon by eating and gaining nutrients. This gives them carbon. They get hydrogen by water and glucose. They get nitrogen from food.
Animals obtain these essential elements through the consumption of food and water on basis of their mode of nutrition. While plants directly synthesize these elements with the help of the process known as photosynthesis.
What are the roles of these four elements?Carbon is considered the building block of living creatures. While other elements like oxygen, nitrogen, and hydrogen are also required by these living entities in order to complete their life cycle, perform growth and development, energy synthesis, metabolism, etc.
The process of obtaining these essential elements in plants and animals differs a lot. This is because the mode of nutrition for both living entities varies.
Plant being autotrophs synthesize their food through photosynthesis and takes essential nutrients from the soil. On contrary, animals get these elements by eating other animals or plant-derived products.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?(this is for gizmos lab carbon cycle)
Answers
Answer: When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere.
9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.
What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?According to the Intergovernmental Panel on Climate Change, the average annual increase in carbon dioxide concentration from 2000 to 2009 was about 1.9 parts per million (ppm) per year, of which about 55% came from the burning of fossil fuels and industrial processes, and about 45% came from land-use change, primarily deforestation.
Thus, in terms of actual amounts, this translates to roughly 9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.

B. Sexual reproduction
C. Mitosis
D. Somatic cells
Answers
Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.

b. it makes progesterone that regulates sperm formation
c. it provides a place for the embryo to attach to
d. it produces gametes that can transport themselves to the egg cell
Answers
Explanation:
human male reproductive system produces gamets known as sperm which are capable of flagellated movement
The male reproductive system produces gametes that can transport themselves to the egg cell. Therefore, option D is correct.
What is the male reproductive system?Tissues, organs, and glands which has important role in the reproduction, together known as the reproductive system. The male reproductive system is made up of internal organs including the prostate gland, vas deferens, and urethra as well as external genitalia like the testes, and scrotum.
The testes are where sperm are manufactured in the scrotum. The epididymis is a tortuously coiled structure topping the testis, and it receives immature sperm from the testis and stores it for several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct
The male reproductive system produces gametes that can transport themselves to the egg cell. Therefore, option D is correct.
