Answer:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?
Answer:
RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.
These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.
Estimate the electric field in the membrane wall of a living cell. Assume the wall is 14 nmnm thick and has a potential of 0.11 VV across it.
Answer:
The electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
Explanation:
Given;
thickness of the membrane wall, d = 14 nm = 14 x 10⁻⁹ m
potential of the membrane wall, V = 0.11 V
The electric field in the membrane wall of a living cell is calculated as;
[tex]E = \frac{V}{d} \\\\E = \frac{0.11}{14 \times 10^{-9}} \\\\E = 7.857 \times 10^6 \ V/m[/tex]
Therefore, the electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.

Compared to skeletal muscle, contraction of smooth muscle cells is a. only a slower response to a stimulus. b. only sustained without fatigue. c. only controlled by the somatic nervous system. d. a slower response to a stimulus and sustained without fatigue. e. a slower response to a stimulus, sustained without fatigue, and controlled by the somatic nervous system.
Answer: d. a slower response to a stimulus and sustained without fatigue.
Explanation:
The activity of the enzyme ATPase is slower in the smooth muscles as compared to the skeletal muscles as a result the production of ATP is also slow this can directly affect the response giving ability of the smooth muscles to the stimulus so there is an delay in the response given by the smooth muscles. The smooth muscle cells are involuntary. They use very little amount of ATP does during energy requirements they sustain without fatigue.

A massive farm near our school has recently had a
decrease in crop production (e.g., not as many plants are
successfully growing). A soil ecologist was notified. She
immediately noticed that there were no worms, bacteria, or
other microorganisms in the soil, even though she knew that
many organisms were present in the soil five years ago. Based
on this information, she would probably say that the population
density of microorganisms had
a. Increased
b. Decreased
c. Immigrated
d. None of the above
Answer:
C. Immigrated
Explanation:
The plants stopped growing, so I imagine the microorganisms moved to find a better food source.

Explanation:
Calcium ion release from the SR, occurs in the junctional SR/terminal cisternae through a ryanodine receptor (RyR) and is known as a calcium spark.
If fertilization started in woman , mensuration will occur or not??? explain
Answer:
Fertilisation happens if the egg cell meets and joins with a sperm cell in the oviduct. The fertilised egg attaches to the lining of the uterus. The woman becomes pregnant, the lining of the uterus does not break down and menstruation does not happen.

when a cell goes through mitosis and cell division, the two new cells have _?
Answer:
D. Same number of chromosomes as the original cell
Explanation:
Mitosis is a kind of cell division which results in two daughter cells that are genetically identical to one another and the parent cell. Mitotic division causes each daughter cell to contain the SAME NUMBER OF CHROMOSOMES as the parent cell.
For example, a somatic human cell contains 23 pairs of chromosomes. If this cell undergoes division by mitosis, the two daughter cells that will result will contain 23 pairs of chromosomes each. This means that the two new cells that results from mitosis have the same number of chromosomes as the original cell.
Name some bubonic plague
Bubonic plague is one of three types of plague caused by the plague bacterium (Yersinia pestis). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin. Occasionally, the swollen lymph nodes, known as "buboes".
Answer:Today, it's best known as the Black Death or the bubonic plague. Medieval people called it "the blue sickness," La pest ("the Pestilence"), and "the Great Mortality." The name bubonic comes from the medieval Latin word bubo via Italian bilbo--meaning a pustule, growth, or swelling.
Explanation:
Austin made the claim that meiosis provides an advantage for sexually reproducing organisms by ensuring genetic variation
Which statement explains why he is correct
A. Meiosis allows the offspring produced during sexual reproduction to grow and develop
B meiosis joins together the sex cell during sexual reproduction to produce new offspring
C meiosis produces sex cells that are joined during sexual reproduction to produce offspring
D meiosis produces the body cells that join to form new offspring during sexual reproduction
Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring
Explanation:
Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.
Answer:
c
Explanation:
:)))))))))help me plsss
Explanation:
1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.
2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.
3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.
Which of the following is not a abiotic factor ?
A. Dirt
B. Sunlight
C. Water
D. Air
Answer:
A) Dirt
Explanation:
Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.
Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.
Answer: They are all Abiotic factors actually but my best guess would be B. sunlight

Biomes are determined by
Answer:
Biomes are determined by their climate which is determined by percipitation and temperature
Explanation:
There are two main factors when scientists define a biome. One is the climate or the long-time average weather of a region. The other is the specific plants and animals in an area. The organisms in a biome often adapt to their environment. There are seven types of biomes based on these factors.
