Answer:
Simple diffusion is a passive transport.
Explanation:
The reason why its a passive transport is because Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
How does exercise build muscles?
Answer:

how are logistic and exponential growth similar?
Answer:
because both are same words
Explanation:
Answer:
Both growth models begin with a population that is growing at a constant rate.
Logistic growth follows a period of exponential growth, as population growth slows or stops.
Exponential growth is only possible when resources are unlimited.
Logistic growth shows what happens when resources become scarce and population growth slows.

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.

After being hunted to near extinction, wolves were reintroduced to Yellowstone National
Park in 1995. After two years, the population of wolves increased rapidly until 2009.
After 2009, the population decreased slightly and has remained at an average of 93
wolves. Which type of growth curve describes the Yellowstone wolves?
A. population density curve
B. exponential growth curve
C. bell curve
D. logistic growth curve
Answer: B: exponential growth curve
Explanation: An exponential growth curve is J-shaped. Exponential growth is more common in R-selected species, which have a short life span and a high rate of reproduction. Yellowstone National Park has 124 wolves living in it.

Briefly explain how genes affecting a polygenic characteristic are located with the use of QTL mapping.
Answer:
QTLs can be identified by using molecular markers associated with the variation of the trait
Explanation:
A Qualitative Trait Locus (QTL) is a chromosomal region correlated with the variation of a quantitative trait, i.e., a phenotypic trait controlled by many genes. QTL mapping refers to the identification of QTLs associated with a particular trait. In QTL mapping, molecular markers (i.e., small and identifiable DNA fragments) are used to develop genetic linkage maps which are further used to discover QTLs. This technique (QTL mapping) consists of evaluating the phenotypic segregation of the trait in the progeny by statistically correlating phenotypes with patterns of genetic segregation (segregation of the molecular markers).
What structure provide shape and support for the cell?
A.Chloroplast
B.Mitochondria
C. cell Wall
D.Golgi bodies
The cell wall provides shape and support for the cell. Therefore, option (C) is correct.
What is cell wall?In the cells of plants, fungi, and some bacteria, the cell wall is a strong structure that encloses the cell membrane. It has a solid and strong structure because it is formed of chitin, which is found in fungi and cellulose in plants. The cell wall supports it mechanically, shields it from harm, and aids in keeping its shape. Moreover, it stops the cell from bursting or collapsing under pressure, which is crucial for plant cells because they must maintain turgor pressure in order to function properly.
Animal cells, on the other hand, lack a cell wall and instead contain a cytoskeleton formed of protein fibers that gives them stability and shape. Organelles that perform photosynthesis include chloroplasts, mitochondria, and golgi bodies, which also produce energy and process and transport proteins inside of cells.

Answer:
I would have to say recharge of the aquifer by using ground water after some precipitation.
Explanation:
Melting snow or rain increases ground water that percolates down to replenish the aquifer.
Elevation changes causes the aquifer to flow up in low spots/springs on the surface. And the cycle repeats through evaporation and plant respiration.

1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.
Answer:
1. Stamen and pistil
2. Pollen, microspore
Explanation:
The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).
The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).
