Answer:
the answer is selective permeability
Explanation:
A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar).

Which tissue(s) is/are prone to injury and heal poorly because the ratio of extracellular matrix to cells is very high?
A. Cartilage.
B. Joint Capsule.
C. Ligament.
D. Bone.
E. Tendon.
Answer:
The correct answer is option E "Tendon"
Explanation:
Tendon associate muscle to bone, conveying probably the most noteworthy powers experienced by any vertebrate tissue, as they encourage development and give skeletal dependability.
The proportion of matrix to-cells in Tendon is hence among the most noteworthy of any vertebrate tissues; in this way understanding grid structure and association, and how cells communicate with lattice, is critical to understanding the capacity, homeostasis and fix of Tendons. While huge advances in our comprehension of Tendon work have been made, major unanswered inquiries stay, for example, how cells build up the Tendon grid and how the matrix association clarifies the mechanical properties of Tendon. This information is an essential for the advancement of novel methodologies to improve Tendon healing in the treatment of tendinopathies.

How does exercise build muscles?
Answer:
Exercise builds and strengthens muscles, which can protect the bones from injury, and support and protect joints affected by arthritis. Strong muscles also give stability and improve balance and coordination. Exercise also improves blood supply to the muscles and increases their capacity to use oxygen

Which statement best describes how a B-cell works?
Answer:
It produces antibodies, which stimulate a fever
Explanation:
B-cells are also known as B-lymphocytes.
Chronic lymphocytic leukemia (CLL or CLL) is a malignant disease of the blood in which lymphocytes, which belong to the white bloodline, grow uncontrollably, thrive, and form their own clones. It is the most common type of leukemia in adults. There are two types: B cell, which is much more common, and T cell, which is rarer.

D. Inner core
Answer:
C?
Explanation:
Maria visited the mountains in Wyoming and became interested in the different ways that mountains and valleys form. How do mountains and valleys develop from a series of normal faults?
A. A footwall slips down to form a valley at a converging plate boundary. Rock on either side of the valley becomes the mountains.
B. Walls of rock grind past each other in opposite directions. This pushes one side up above the other to form the mountains.
C. Compression causes rock to fold and bend, but not break, in the middle of a plate. The rock that folds upward becomes a series of mountains.
D. A hanging wall slips down at a diverging plate boundary. The slab of crust that falls forms a valley, and the slabs on each side form mountains.
Answer:
A
Explanation:
Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another.

If a species has a 2n number of 18, how many autosomes would their SOMATIC cells have?
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.
explain how precipitation affects the phosphorus cycle
Answer:
Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
Explanation:
The precipitation affects the phosphorus cycle in many ways where the soil erosion will take place if the precipitation happens then the weathering of rocks along with the soil getting off will make the nutrients loss in the soil.
What is the cycle of rain called as ?
The cycle of the rain is called as water cycle where the evaporation along with the condensation takes place.
If the precipitation level in the atmosphere is increased then in this case it will increase the transportation of phosphorus along with the other nutrients into soil along with the water sources and the coastal areas as well.
The main reasons of such scenario is because of the deforestation, loss of habitat by the continued invasion of human activities in the natural resources. The reduction of nutrients loss in soil makes an huge impact over the phosphorus cycle.

Carbon dioxide is colorless, odorless gas. Why is it considered a pollutant?
Explanation:
carbon dioxide is a colorless odorless gas formed when substances contain carbon such as Federal gas coal and wood are burned with insufficient supply of air
Answer:
it can be harm full to humans I think and it is not in the chemical compound for air
Explanation:
the EPA stressed that it considers CO2 and other so-called greenhouse gases to be pollutants because of their role in propagating climate change, not because of any direct health effects. But despite continued pressure from environmental groups, the administration never moved to regulate the gases.

What causes surface currents to move? Do you think surface currents have an effect on deep ocean currents?
Answer:- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
