How Human sex gets decided?
Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.
Therefore, Two or more genes are required to determine a polygenic trait. Thus, option B is correct.

Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

A major freeway runs along a stretch of the ocean shore. Over time, scientists begin to
notice a decrease in the number of intertidal organisms. Which of the following is the most
likely cause of the problem?
O A. toxic waste spilled during accidents on the
road
B. runoff of oil and other chemicals from the
road
C. wastewater from the city across the
freeway
O D. Any or all of the above could be causing
the problem.
Answer:
D. Any or all of the above could be causing the problem.
Explanation:
Pollution has been said to have adverse effect on living organisms. In this question, a decrease in number of intertidal organisms has been observed. Since a major freeway runs along a stretch of the ocean shore, the most likely cause of the death of the intertidal organisms is the release of any form of toxic waste into the water body.
Oil pollutants causes death of living organisms by hindering the entrance of oxygen into the water body. It makes it difficult for oxygen, which is a requirement for life, to penetrate the water body. Hence, living organisms in the water body will suffocate and die.
Toxic wastes also causes the death of organisms when ingested in excess. Waste water causes deterioration in the oxygen content of the water body. Hence, any or all of the above options can likely cause the reduction in number of the intertidal organisms.

what is the function of the turbine in a nuclear reactor?
Answer:
The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.
Explanation:
The function of the turbine in a nuclear reactor is to circulate the water to the reactor after energy is removed from it to produce electricity. The correct option is A.
What is a nuclear reactor?A nuclear reactor is a gadget used to initiate as well as control a fission nuclear chain reaction or nuclear fusion interactions.
Nuclear reactors are employed in nuclear power plants for electricity generation as well as in nuclear marine propulsion.
A nuclear reactor, or power plant, is a sequence of machines that can control nuclear fission to generate power. Pellets of the element uranium are used as fuel in nuclear reactors to produce nuclear fission.
The heat generated in the reactor core by nuclear fission is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.

Which of the following best compares viral reproduction to reproduction in other organisms?
A. Viruses do not contain genes that are replicated and passed on.
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce.
C. Viruses and single-celled organisms use mitosis as a reproductive process.
D. Viruses can only reproduce asexually while other organisms have a choice.
Answer:
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce
Explanation:
Virus is an organism that is incapable of replicating on its own without infecting a living host cell. A viral cell is dependent on a living host to replicate and express its genes. Hence, the infection cycle of a virus is its reproductive life cycle.
Other living organisms e.g plant, bacteria, fungi etc. have the ability to reproduce i.e. multiply on their own through asexual or sexual means. However, on the contrary, a virus must infect a living host, hijack the replicational abilities of the host cell in order to reproduce. Based on this, a virus employs a lysogenic or lytic cycle or both on its host to reproduce.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.
