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.

2. Think about an animal like a rhinoceros, a deer, or an antelope. What parts of their body other than their hair must be composed of quite similar material to your nails and hair
Answer:
horns and hooves
Explanation:
horns and hooves are made of kerotin, just like nails and hair.
Keratin is the protein that composes the external layers of the epidermis. It can be found in elements like feathers, nails, and hair. Other parts of the body that might be composed of keratin are horns and hooves.
-------------------------------------
Keratin is a fibrous protein that can be found in epithelial cells that cover internal and external surfaces.
Keratin is the main component of horns, hooves, feathers, hair, and nails.
Horns are hollow and pointed structures that emerge from the skull of the animal.
Animals get born hornless. As they grow they develop these structures. Most of them complete the development near the reproductive stage of the animal.
At sexual maturity age, competitive interaction increases, and animals use them to defend themselves and hurt the opponent. Males of some species also use them to attract females.
Hooves are very developed nails that cover the ugunaltes' fingers. These animals only use the extreme of the fingers to walk.
Like all nails, hooves grow continuously and wears out as the animal walks or runs.

You are looking at the side of a cliff with many horizontal rock layers. In the upper layers you find fossils of rodents, but in layers further below you find amphibians but no rodents. In some still-deeper layers there are neither amphibians nor rodents but there are fossils of beetles and other insects. In the deepest layers you find no insects but you do find millipedes. This fossil evidence suggests that
Answer:
millipedes were the first of these animal groups to evolve.
Explanation:
Fossils are structural remains of animals from the past. As these animals die, it takes years for the remains to be buried.
The millipedes are at the lower layer of the rock, next to insects, amphibians, and then rodents. This shows that millipedes existed and evolved before the rest of the found animal fossils.

Compact bone contains cylinders of calcified bone called ______________________. These cylinders consist of 4 to 20 Compact bone contains cylinders of calcified bone called concentric rings of bone known as:___________________.
a. osteons, canaliculi
b. lamellae, canaliculi
c. osteons, lamellae
d. Haversian canals, lamellae
e. none of the above
Answer:
The correct answer is c. osteons, lamellae
Explanation:
An osteon is the basic functional unit of the cortical bone of a tubular bone. An osteon consists of a central canal that contains two vessels of Havers. Concentric bony laminae are arranged around this canal. These lamellae consist of bone cells and the surrounding base substance. Between the Havers canals there are Volkmann canals that connect the Havers canals. The construction of the cortical bone in these functional units has not yet been fully clarified. In general, it is assumed that these structures serve primarily to deliver tissue and signal transduction. This structure is also supposed to serve the stability and adaptability of the bone.
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).
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.

Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely
eliminating those risks.
Answer:
Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers. The more practical approach is to minimize and manage the health risks associated with chemical exposure.

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.

The amount or number of chemical substances or molecules that are present before the progression of reaction are known as reactants.
While after the successful progression or completion of a specific chemical reaction such reactants are performed into another, these substances or molecules are known as products.
Both the molecules of reactants and products possess some sorts of chemical identity in order to distinguisg from each other.
