Explanation:
In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive yA plant with genotype Yy and a plant with YY are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint. Draw a Punnett square to help you determine the answer) OA. 0 OB. 3 Oc. 1 OD. 2
Answer:
Its 1 I just took the test and answered 0 and got it wrong
Explanation:
If two plants with yellow leaves with YY and Yy genotypes are crossed then all the offspring will have yellow leaves. Thus, the correct option is A.
What is a Monohybrid cross?A monohybrid cross is the hybrid of the two individuals with homozygous genotypes or heterozygous genotypes which result in the formation of opposite phenotype for a certain genetic trait. The cross between the two monohybrid traits such as flower color or plant height is called a Monohybrid Cross.
When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.
Therefore, the correct option is A.

Explanation:
Carbon is unique due to the carbon atom’s
Answer:
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
Explanation:
What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

Explanation:
What is the reason of dividing Endoplasmic Reticulum Into two types.
Explain in detail.
Please answer
Answer:
We divide ER into two types because Smooth ER(SER) do not have ribosomes and Rough ER(RER) have ribosome thus former is also called Agranulated ER and Latter is called Granulated ER. SER is not involved in protein synthesis its main function is synthesis of lipids carbs steroid thus it is found in Adipose cells, interstitial cells, liver cells. RER have ribosomes so they are involved in protein synthesis so they are present in protein synthesising cells such as salivary glands and pancreas.

Which of the following statements is true for a molecule that is phosphorylated?
A) It has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B) It has a decreased chemical energy and is less likely to provide energy for cellular work.
C) It has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate .
D) It has increased chemical potential energy that may be used to do cellular work.
Answer:
The correct appropriate is Option D.
Explanation:
The phosphorylation mechanism of both a chemical compound, either through inorganic phosphate conversion other than by phosphate conversion from yet another biological phosphate. Those have improved chemical energy capacity which could be used to do cellular function.Some other possible alternatives are not connected to the situation described. So, the solution above is the right one.
The statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).
Phosphorylation is a posttranslational protein modification that plays a fundamental role in many cellular processes.Phosphorylation increases the potential energy of a molecule by adding a phosphate group that contains a high-energy phosphate bond.The energy released by this phosphate bond can be used to drive many cellular processes.In conclusion, the statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Besides poaching, what other major factor is causing a decline in elephant populations?
Answer:Habitat Loss and conflict with communities
Explanation: Habitat loss and conflict with communities
Most elephant habitat still extends outside protected areas, and the rapid growth of human populations and the extension of agriculture into rangelands and forests formerly considered unsuitable for farming mean that elephant habitat is continuing to be lost.
Increasing conflict with people
As human populations expand, more land is being converted to agriculture. So elephant habitat is shrinking and becoming more fragmented, and people and elephants are increasingly coming into contact - and conflict - with each other.
Elephants sometimes raid farmers’ fields and damage their crops – affecting the farmers’ livelihoods – and may even kill people. Elephants are sometimes killed in retaliation.
With human populations continuing to grow across their range, habitat loss and degradation - and conflict with communities - will remain major threats to elephants' survival.
Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.
What are the reason behind the decline of the population of elephants?The reason behind the decline of the population of elephants are poaching, besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.The logistics growth curve has been defined as the population per capita growth rate is decreases and get smaller and the size of population increases maximum applied by resources which are limited in the environment which is known as the K that has been carrying capacity.
The logistics population growth has been represented by the logistic growth curve on a line graph and the shape of the curve has S - shaped that represents the slow increase, and rapid growth in the population and after that there has been reduction in the growth.
The best example of the logistics growth has observed in the wild population that includes the sheep as well as harbor seals. In both of the cases the number of the population has been increases and carrying capacity for small period of time.
Therefore, Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.
