Explanation:
ORNAMENTAL PLANTS are defined as those plants that has outstanding and unique flowers, fragrance an interesting shape, colorful or unusual bark, excellent fall color, or a combination of these and other features. While some of these plants add framework and structure to the garden and provide at least a little shade.; others also make great background plants for shrub and flower borders.
HORTICULTURISTS are individuals that deals with the aspect of agriculture which involves the cultivation of plants, vegetables, fruits, flowers, herbs, ornamental trees, maintaining nurseries, gardens, orchards and plantations. To be more specific, ornamental horticulturist are those that works with plants used in decoration or recreation, which is mostly done at a nursery, floral shop, landscaping or office surroundings.

B. Heart attacks reduce blood flow to the heart and cause coronary artery disease.
C. Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
D. Heart attacks occur when coronary artery disease is treated.
C) Coronary artery disease can reduce blood flow to the heart and cause heart attacks
CAD (or atherosclerosis) affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower. And due to inadequate supply of blood, the heart muscles get damaged. This can lead to a heart attack!
Which of the following parts of a prokaryote is the part of the cell membrane that is folded in and thought to be used
for helping DNA replicate?
A. Mesosome
B. Genophore
C. Peptidoglycan
D. Cell wall
Answer:
a
Explanation:
: an organelle of bacteria that appears as an invagination of the plasma membrane and functions either in DNA replication and cell division or excretion of exoenzymes.
The following part of the cell membrane that is folded in and thought to be used for helping DNA replicate is the mesosome. The correct option is A.
What is mesosome?Mesosome is a round organelle that is present in prokaryotic organisms like bacteria. These organisms present as introversion in the plasma membrane. This organ helps in many functions of the cell like DNA replication and cell division.
DNA replication is a process of replicating DNA in other cells. It happens in the process of cell division. In bacteria cells, mesosomes help in the distribution of DNA into the daughter cells during the division.
Thus, the correct option is A. Mesosome regarding the organelle present in the bacteria helps in DNA replication.

Explain the self-correcting nature of science.
The notion of a self-correcting science is based on the naive model of science as an objective process that incorporates new information and updates beliefs about the world depending on the available evidence. When new information suggests that old beliefs are false, the old beliefs are replaced by new beliefs.

Answer:
Exchange of materials between organisms and their environment
Explanation:
These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

Which answer option below describes the best way to increase the accuracy of a
confidence interval calculation?
The accuracy of a confidence interval calculation can be increased from 95% to 99%.
Thus, option C is correct.
What is confidence interval?A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.
The proportion of the range consists of the true value of the factor that will be identical to the confidence level.
In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.
It cannot estimate the plausible values of the unknown parameter of the population.
Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.
Secondly, the precision defined in terms of the width of a confidence interval.
Hence, option C is correct.

explain how the mammalian skin perform it's role as a thermoregulatory
Answer:
The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.

The immunoglobulin light chain does not have a D segment. In humans, there are two different possible light chain proteins, termed kappa and lambda. Assume that there are 35 V segments and 5 J segments in the human kappa light chain region, and there are 30 V segments and 4 J segments in the human lambda light chain region. How many possible light chain genes can be created from these different segments, simply due to combinatorial diversity
Answer:
295
Explanation:
Antibodies (also known as immunoglobulins) are immune system-related proteins that circulate in the bloodstream in order to recognize pathogenic harmful substances (antigens) and neutralize them. An antibody consists of two immunoglobulin heavy chains and two immunoglobulin light chains. There are two types of immunoglobulin light chains: 1-the kappa (κ) light chain, which is encoded by the immunoglobulin κ locus; and 2-the lambda (λ) light chain, which is encoded by the immunoglobulin λ locus. The immunoglobulin light chain is a multidomain protein composed of two domains: 1- the N-terminal variable (V) domain and 2-the C-terminal constant (C) domain. V(D)J recombination is a type of somatic rearrangement process by which T and B cells can assemble different gene segments, which are referred to as variable (V), diversity (D) and joining (J) gene segments. In the question above the number of possible genomic recombination events between immunoglobulin gene segments can be calculated as >> (5 x 35) + (4 x 30) = 295.

Answer:
EeWw
Explanation:
This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for unattached earlobes but homzygous recessive for hairline i.e. (EEww).
The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:
eeWW - eW, eW, eW, eW
EEww - Ew, Ew, Ew, Ew
Using these gametes in a punnet square, the following proportions of offsprings will likely be produced:
All EeWw offsprings

possible.
Answer:
I predict that the gametes will be unique from their parents.
Explanation:
I predict that the chromosomes will pair up, with each pair having a red chromosome and a blue chromosome, then they'll cross over and exchange similar genetic information with each other. I think this because variety is important for any species for survival.
