Bacteria are organisms that reproduce asexually. How is it better for them than reproducing sexually.
Answer: they don't have a reproductive system
Explanation:
The structural integrity of bacteria is to peptidoglycan as the structural integrity of plant spores is to
Answer:
Lignin.
Explanation:
The structural integrity of plant spores is lignin that is present in many parts of the plant. This lignin provides hardness to the plant body which help them to stand the plant erect. If this lignin is not present in the plant body the plant will not stand erected. This lignin is present in large amount in the stem of plant body so that's why the lignin provides structural integrity to plant spores
Severe combined immunodeficiency (SCID): Group of answer choices is a result of the absence of macrophages or B cells. affects only part of the adaptive immune response. can be caused by failure of TAP transporters. is caused by the lack of T cell and B cell maturation/differentiation.
Answer:
is a result of the absence of macrophages or B cells.
Explanation:
Severe combined immunodeficiency (SCID) results due to the absence of macrophages or B cells that is responsible for the immunity of our body. Severe combined immunodeficiency (SCID) is an inherited immunodeficiency disease (PIDD) that presents in infancy results in a weak immune system that is unable to fight against even mild infections so due the absence of macrophages or B cells, the body is vulnerable to diseases.

Which of the following statements describes the conditions of a pneumothorax? View Available Hint(s) Which of the following statements describes the conditions of a pneumothorax? The intrapulmonary pressure equalizes to atmospheric pressure. Both lungs partially or completely collapse. The intrapleural pressure decreases. The presence of air in the pleural cavity.
Answer:
The presence of air in the pleural cavity
Explanation:
A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

The automatic control systems that control our temperature, pH, ions, and blood sugar is called:
A. Immune system
B. Homeostasis
C. Homeopathy
D. Regulatory system
Answer:
The correct answer is - B. Homeostasis.
Explanation:
Homeostasis is the automatic control system that maintains optimal conditions for enzyme action in the complete human body, and other important functions such as hormonal response and others.
In the human body, homeostasis includes the control of temperature, pH, ions, and blood sugar with help of various enzymes, hormones, and sensory organs.
Answer:
Homeostasis
Explanation:
When calcium levels in the blood are too low, the body releases a hormone that removes calcium from the bones. A person who suffers from a certain type of thyroid disease will often have low blood calcium and brittle bones because the body is taking the calcium from the bones. The afflicted person will typically see an endocrinologist, who studies hormones, and an orthopedist, who studies bones. What do these two doctors have in common
Answer:
They both would need to check the calcium levels
Explanation:
The two doctors would both need to check the calcium levels of the patient.
While the endocrinologist would need to check the calcium level in the blood, the orthopedist would have to check the calcium level in the bones of the patient.
Most endocrine disorders are caused by abnormal calcium levels in the blood while the bones are largely made of calcium. Hence, both doctors would usually need to work with the calcium levels in the blood and bones respectively.

Which of the following is an example of the endocrine system maintaining homeostasis?
1. Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response
2. Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
3. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
4. Using sense organs to get information about the outside world and direct an appropriate body response release
Answer:
The correct answer is "C".
Homeostasis is the maintaining of stable internal conditions in the body of a living being, such as body temperature or heart rate.
The endocrine system is an organ in the body which is in charge of secreting hormones that regulate numerous functions in the body, including metabolism, growth, sexual function, sleep, and mood among others. It is an essential organ which contributes to the state of homeostasis in the body.

1. How does scientific inquiry differ
from simply asking questions?
Answer:
inquiry means more than asking questions. Inquiry is a process of investigation, with thoughtful questions leading to a search for answers. Asking questions is a natural activity for all curious minds, but even figuring out what to ask takes practice.
The scientific method is the process that scientists use to find out new information. It involves a question, a hypothesis, a prediction, collecting data, and analyzing that data to make a conclusion. How would you use the scientific method to answer this question: Do mice live longer when they are fed high-sugar diets? (15 points)
Answer:
Science deals with emperical to finding solutions to problem
Explanation:
This research should be subject to case study. You will select two groups of mice. One group with high feed of sugar diet and second group with a minimum diet of sugar. You will study the two groups in order to know which one lives longer

nutrients in the soil is the correct answer
The correct answer is option (c) nutrients in the soil.
What is biotic and abiotic factors ?
Biotic and abiotic are the two essential factors responsible for shaping the ecosystem.The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions and chemical agents in an ecosystem. Therefore, both the abiotic and biotic resources affect the survival and reproduction process.

Part Two: Position Paper What's your position about building roads in the rainforest? Write a paper that explains your position. Use facts from your research to support your position. How would humans and different parts of Earth be affected by the construction? Is there any argument against your position?
Answer:
We should not be building roads in the rain forest. Some reasons behind this include trees produce oxygen, animals leaving their natural habitat would not survive, and it would only increase pollution. Research states that if pollution increases any more, the Ozone protecting us will deteriorate. Other research states that if animals lose their natural habitat and have to adapt to a new environment, they are not very likely to survive. And not surviving means that the food chain will break, affecting everything above it, and that could also include us. This concludes why we should not build roads in rain forests.
Explanation:
Sorry if its short, but here <3
No roads should be build in the rainforests.
What do you mean by rainforests?
"A luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall."It's a moisture dependent vegetation.Why no roads?To build a road a vast area full of vegetation will be cut down.This will adversely affect the climate and habitats of organisms living there.This will also result in scarcity of rainfall.This results in interference of humans on the habitat of that area.Hence, building of road should be avoided in rainforests.

Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
