Explain the relationship between the number of daylight hours and seasons.
Explanation:
The tilt of the Earth's axis also defines the length of daylight. Daylight hours are shortest in each hemisphere's winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.

state the role in the menstrual cycle of the following hormones, FSH, LH, estrogen and progesterone
Answer:
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are called gonadotropins because stimulate the gonads - in males, the testes, and in females, the ovaries. They are not necessary for life, but are essential for reproduction.
Explanation:
The function of estrogen & progesterone is Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization.
According to the periodic table, which of the following is the most accurate model of an atom of boron?
Answer: boron has 5 protons and 6 neutrons
Explanation:
According to the periodic table, the model of an atom that describes an atom of boron is model A. Boron has 6 neutrons and 5 protons.
What is a periodic table?
The chemical elements are arranged in rows and columns in the periodic table, also called the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences, and is frequently regarded as a symbol of chemistry.
The atomic number is the number of protons, which is characteristic of a chemical element. The atomic number increases from left to right in the Periodic table.
Boron is an element with atomic number 5, which means it has 5 protons and 5 electrons, boron atom has a neutral charge.
The electron configuration of boron: ₅B: 1s² 2s² 2p¹, it has three valence electrons in 2s and 2p orbitals.
Therefore, the correct option is A, model A. Boron has 6 neutrons and 5 protons.

Explain the process of nuclear fusion. How many hydrogen atoms combine to form a single helium atom?
Answer:
The Hydrogen Fusion Process In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. This is the simple version of the story. There are actually electrons, neutrinos and photons involved that make the fusion of Hydrogen into Helium possible.
Explanation:
Answer:
This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy

An Important step in the process of translation is
Answer:
The steps in translation are:
The ribosome starts matching tRNA anticodon sequences to the mRNA codon sequence. The ribosome continues until it hits a stop sequence, then it releases the polypeptide and the mRNA. The polypeptide forms into its native shape and starts acting as a functional protein in the cell.
Explanation:
Describe the inputs and outputs of photosynthesis.

Explanation:
________ proteins or channel proteins are used to aid substances across the cell membrane in passive transport
Answer: channel proteins
Explanation:
Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane. A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane.

Answer:
The answer is C, the sun's rays cause mutations in the skin cells.
Explanation:
Answer:
B. The heat from the sun interrupts the cell cycle
Explanation:
Too much UV radiation from the sun or sunbeds can damage the genetic material (the DNA) in your skin cells. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
magma-hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
igneous rocks- Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

Dogs and wolves are more closely related to each other than either is to cats.
Explain how you would separate these organisms into clades.
Answer:
I would split these organisms into two paraphyletic groups: 1-one group composed of wolfs and dogs, and 2-one group including all three species (dogs, wolves and cats).
Explanation:
A clade is by definition a monophyletic group, it means that a clade is a group composed of a common ancestor and all its lineal descendants. Moreover, a paraphyletic taxon is a group of organisms that share a most recent common ancestor and some of its descendants. In this case, wolves and dogs can be grouped to form a more inclusive group since both species belong to the same genus (Cani), while dogs, wolves and cats can be grouped to form a major group because these three species are mammal species. In consequence, in this case, we have two paraphyletic groups supported by synapomorphic (shared, derived) characters, since wolfs and dogs represent only two species within genus Canis, while dogs, wolves and cats represent three species within class Mammalia.

How are mutations and natural selection related?
Answer:
The genetic variation that occurs in a population because of mutation is random — but selection acts on that variation in a very non-random way: genetic variants that aid survival and reproduction are much more likely to become common than variants that don't. Natural selection is NOT random!
