Answer:
The correct answer is - external fertilization.
Explanation:
It is the contrasting fertilization process to internal fertilization as external fertilization takes place outside of the female body where eggs released in surrounding environment of the female and fused with sperms released by the male.
In frogs, the type of fertilization is the external fertilization process where the female frog released her eggs in water and sperm solution covers the eggs and fertilizes them.

Which 2 of the Earth's regions contain the most carbon?
Answers
Answer:
The amount of carbon stored in a particular system is called a “stock” or a “pool”. The Earth's largest carbon stock is found within the continental crusts and upper mantle of the Earth, a large portion of which is sedimentary rock formed over millions of years (2).
Peridotite, quartz, and nickel are some of the most common compounds that make up Earth. Peridotite has a density of approximately 3.4 g/cm3; quartz has a density of approximately 2.65 g/cm3; and nickel has a density of approximately 8.9 g/cm3. Based on this information, which compound do you think is most common near Earth’s surface, and which do you think is most common near Earth’s core?
Answers

Earth is made up of three main layers and we human beings live on the solid outer layer called the crust.
Which alloy is present in the core of earth?The outer core is about 1,400 miles thick, and made up of mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. Quartz is probably most common at the surface.
These metals can be found on the surface of earth in solid form. In the outer core, metal present in a very hot liquid form between 7,000-9,000º F.

Which of the following examples is a non-renewable source of energy A.Wind B.hydroelectric C.Nuclear power D.Wood
Answers
Answer:
An example of non-renewable source of energy would be C) Nuclear power.
Explanation:
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, whilst Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
I hope this helps! Have a great day! -Olli :]
Nuclear power is a non-renewable source of energy. It is derived from the energy released by nuclear reactions, which are fueled by radioactive materials such as uranium or plutonium. Therefore, option (C) is correct.
What is nuclear power?Nuclear power is a form of energy that is generated from nuclear reactions. It involves the use of radioactive materials, such as uranium or plutonium, which undergo nuclear fission in a reactor to produce heat. This heat is then used to generate steam, which drives a turbine and produces electricity. Nuclear power plants are used to generate electricity for homes and businesses, and they are typically very efficient and reliable sources of energy.
However, nuclear power also has potential drawbacks, including the risk of radiation leaks or accidents, the long-term storage of radioactive waste, and concerns over nuclear proliferation. Despite these concerns, nuclear power remains an important component of the world's energy mix, and ongoing research is focused on developing safer and more sustainable nuclear technologies.

how is hydro electricity produced step by step explanation
Answers
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.

Colorblindness is sex recessive A female who is heterozygous for -green color blindness normal male. What is the chance the boys wil be colorblind Do the Punnett Square!
Answers
Answer:
The correct answer is - 50% of boys will be colorblind.
Explanation:
Colorblindness is an X-linked recessive disorder which means it will affect a female if present in both X chromosomes whereas in males there is only one X chromosome so even one chromosome with the mutated gene will cause the disorder.
Cross: heterozygous female (XHXh) with a normal man (XHY)

Answers
Answer:
C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
Explanation:
It's not A, because that's the nervous system, not endocrine.
It's not B, because homeostasis = balance, and not stopping production isn't balance
It's not D, because that's the nervous system again.
The endocrine system governs hormones.

What is meant by signal transduction and what is its effect on the process of egg activation?
Answers
Answer:
The process by which a cell responds to substances outside the cell through signaling molecules found on the surface of and inside the cell. ... Signal transduction is important for cells to grow and work normally. Cells that have abnormal signaling molecules may become cancer cells. Also called cell signaling.
Egg activation, whether initiated by or independent of fertilization, induces a rise in intracellular calcium. This calcium increase often manifests as a signaling wave that traverses the egg and releases it from meiotic arrest and metabolic dormancy.
What is the general shape of the graph?
Cell division gizmo
Answers
Answer and Explanation:
The image attached below presents the general shape of a graph showing cell division. This is because this graph shows the diversification of the amount of DNA in a cell in relation to the time and phases of cell division.
Through the graph shown below, we can see that before cell division, the cell passes through the G1 phase, where it has a specific amount of DNA for a cell in that cell stage. During phase S there is a progressive increase in the amount of DNA, and at the end of that phase, the cell will have twice as much DNA as it had before. The end of phase S, starts phase G2, where the amount of DNA is stabilized, until cell division occurs (represented in the graph by the letter M). Cell division causes a progressive decrease in the amount of DNA, which returns to the amount shown in phase G1.
