in a hardy-weinberg population with two alleles a1 and a2 that are in equilibrium, the frequency of the allele a2 is 0.3. what is the frequency of individuals that are homozygous for this allele?
There are 32 people that are homozygous for this allele in the population.
The Hardy-Weinberg equation states that p + q = 1 thus the sum of allele frequencies for all the alleles at the locus must be 1. Additionally, the Hardy-Weinberg equation is written as follows: p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is the population's frequency of the "a" allele.
The frequency of the homozygous genotype AA is represented by p2, the homozygous genotype AA is represented by q2, and the heterozygous genotype Aa is represented by 2pq in the equation.
Here, q = 0.2. In light of this, p = "1- q = 1 - 0.2 = 0.8.
As previously stated, the population of heterozygous individuals will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.

what prevents coral reefs from surviving below the euphotic zone? group of answer choices high water density high pressure inadequate sunlight saline water damage from storms
Inadequate sunlight prevents coral reefs from surviving below the euphotic zone.
The majority of coral reefs are found nearby in shallow water. Due of this, they are particularly susceptible to the negative consequences of human activity, both directly via the exploitation of reef resources and indirectly through the effects of nearby human activities on land and in the coastal zone. The social, cultural, and economic fabric of local coastal communities is intricately intertwined with many of the human activities that harm coral reefs.
Numerous local risks to coral reefs exist, such as:
Physical harm or devastation caused by recreational overuse, coastal development, dredging, quarrying, harmful fishing methods and equipment, boat anchors and groundings, etc (touching or removing corals).

When you solve the equation for A, you are making A the subject of the equation. It becomes A = B + 1 + P.
Change of subject of equationsChanging the subject of an equation for a specific component requires the component is made the subject.
In the equation: P = A - B - 1
In order to make A the subject, it has to be carried across the other side of the equation. When this is done, we will have:
P - A = -B - 1
Next would be to move P to the other side of the equation. When you move P to the other side, we have:
- A = -B - 1 - P
Divide both sides by negative in order to cancel out the - sign on A. What we will have left is:
A = B + 1 + P

The annual fluctuation in carbon dioxide concentration can best be explained by the.
Answer:
Leaf area development, photosynthetic rate, and source-sink ratio responses are considered to be the three main determinants of photosynthetic activity.
Different growth habits on leaf number and blade size are identified as a result of leaf area development in response to stress.
Thus, Option D is correct.
Photosynthesis: 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP
Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (O₂).
Explanation:
Why is photosynthesis affected by temperature?
The rate of photosynthesis is influenced by temperature. As the temperature rises, photosynthesis proceeds more quickly. This is so because photosynthesis is a chemical reaction, and warmth usually speeds up chemical reactions.
As winter draws near, leaves begin to lose their chlorophyll, and the tree saves its contents for recycling, namely nitrogen, magnesium, and phosphates. The nutrients are transferred from the leaves back into the branches and are then deposited in the bark of those branches.

due to their chemistries, are hormone whose receptor will be inside the cell, while hormones will have their receptor on the cell membrane.
Steroid hormone are hormone whose receptor will be inside the cell and Protein hormones have their receptor on the cell membrane
Contrary to steroid hormones, which are lipid in composition and can easily enter the cell, proteinaceous signaling molecules must have their receptors anchored in the plasma membrane since proteins cannot cross the membrane. The receptor for protein hormones is membrane-associated and embedded in the plasma membrane of the cell's surface. When a hormone interacts with a receptor, a series of secondary effects are frequently triggered in the cell's cytoplasm.
These effects can include the phosphorylation or dephosphorylation of numerous other cytoplasmic proteins, modifications to ion channel permeability, or elevated levels of intracellular molecules that may serve as secondary messengers. Target cells include steroid hormone receptors on their plasma membrane as well as in their cytoplasm and nucleus. They are typically nuclear or cytoplasmic intracellular receptors that start signal transduction for steroid hormones and cause changes in gene expression over the course of hours to days.

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef. This has something to do with durion
The sharp increase in water temperature due to global warming drives zooxanthellae death. Corals lose their symbiotic algae and suffer bleaching due to the lack of photosynthetic organisms that provide them with color.
What is the algae-coral relationship?Corals are naturally translucid or white organisms. However, they look brightly colored because they host symbionts with colorful photosynthetic pigments.
Corals can host different organisms that live on and among them, giving place to amazing ecosystems.
The photosynthetic unicellular microalgae zooxanthellae are symbionts to the coral.
Corals provide shelter and protection to the algae, and nutrients like carbon, phosphorous, and nitrogen.Algae provide photosynthetic products like oxygen and sugars, and also give color to the corals.This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
Global warming increases water temperature significantly, which makes the bond between algae and coral break because of algae death. The lack of algae means an increase in coral bleaching since there are no photosynthetic organisms that provide them with color. Besides, the absence of algae means no availability of photosynthetic products.

What is Telophase ?
The fifth and final stage of mitosis, known as telophase, is when a parent cell's replicated genetic material is split into two identical daughter cells. Once the duplicated, paired chromosomes have been split apart and brought to the cell's poles, or opposite sides, telophase has begun. To isolate the nuclear DNA from the cytoplasm, a nuclear membrane develops around each set of chromosomes during telophase. The chromosomes start to uncoil, becoming less compact and dispersed. The cell goes through a process known as cytokinesis, which separates the cytoplasm of the parental cell into two daughter cells, along with telophase.
