The Moon orbits Earth once every 27.3 days and spins on its axis once every 27.3 days. This means that although the Moon is rotating, it always keeps one face toward us.
What is rotation?Rotation refers to an object's spinning motion about its own axis and revolution refers the object's orbital motion around another object.
It is also known as synchronous rotation this is why we only ever see the Moon's nearside from Earth.

B.Packaging proteins
C.Forming lipids
D.Producing energy
Energy production in cells occurs as a result of oxidative phosphorylation in the mitochondria.
The correct answer is D
What are the mitochondria's primary roles?Membrane-bound cell organelles known as mitochondria (mitochondrion, singular) produce the majority of the chemical energy required to fuel cellular metabolic operations.
What occurs if the mitochondria fail to function?The lack of energy in the cells is caused by damaged mitochondria. Damage is caused by the cells' accumulation of unneeded oxygen and fuel molecules. Different mitochondrial diseases can have different symptoms. It relies on the number of faulty mitochondria and their location in the body.

What is the original source of variation that natural selection can act upon?
The original source of variation that natural selection can act upon is genetic diversity in a population, which comes from mutation and sexual reproduction.
Explanation:The original source of variation that natural selection can act upon is primarily genetic diversity in a population, which comes from two main sources: mutation and sexual reproduction.
Mutation, a change in DNA, is the ultimate source of new alleles or new genetic variation in any population. It can result in an individual having a trait different from other individuals. The changes caused by mutation can provide beneficial, harmful or neutral effects on an organism's phenotype which is a critical aspect for natural selection.
Sexually reproducing species also contribute to genetic diversity through unique combinations of alleles assembling to produce unique genotypes in offspring. Natural selection can only act if there is variation among individuals in a population, and this variation must be genetically based.

Which description best contrasts skeletal and smooth muscle tissue? Skeletal muscle tissue contains no bands, whereas smooth muscle tissue is streaked with bands. Skeletal muscle tissue stores energy and blood, whereas smooth muscle tissue controls movement. Skeletal muscle tissue regulates muscles attached to bones, whereas smooth muscle tissue regulates the heart. Skeletal muscle tissue controls voluntary movements, whereas smooth muscle tissue controls involuntary movements.
Skeletal muscle tissue controls voluntary movements and has a striped appearance, while smooth muscle tissue controls involuntary movements and lacks the striped appearance.
Explanation:The best contrast between skeletal and smooth muscle tissue is that skeletal muscle tissue controls voluntary movements while smooth muscle tissue controls involuntary movements. Skeletal muscle tissue forms skeletal muscles, which attach to bones or skin and control locomotion and any movement that can be consciously controlled. They are also characterized by their striped or striated appearance under a microscope due to the regular arrangement of contraction proteins. On the other hand, smooth muscle tissue occurs in the walls of hollow organs like the intestines, stomach, and blood vessels, and it controls involuntary movements. Smooth muscle does not have the banded or striated appearance because their cells are arranged in sheets instead of bundles, and each cell has a single, centrally located nucleus.

from where do the gems used in jewelry come?
A. They are non-metallic silicate B. They are metallic minerals C. They are non-metallic minerals D. They are metallic ore
The gems commonly used in jewelry come from mining efforts and are usually classified as non-metallic minerals.
Jewelry uses a wide variety of gems and other valuable elements such as:
Sapphires EmeraldsGoldSilverTopazand many more. These gems and elements all have distinct properties and therefore classifications.
Gold and silver are considered metallic ore. They are mined and have properties of metals. One of these defining properties is that both gold and silver may be melted and used to produce other substances. However, though they are used in jewelry, they are not considered to be gems.
Gems in jewelry are those that cannot be melted into other substances and have only a dull, submetallic shine, except the diamond. Gems are unique and desired for their colors. Their lack of shine comes from their relatively low refractive index. This is a property common to nonmetallic minerals. Therefore option C is correct.

Select the part of the ATP molecule that stores and releases energy.
A
B
C
D
Answer:
The correct answer is B.
Explanation:
ATP stands for adenosine triphosphate. ATP is considered as the energy currency of the cell because it provides lots of energy during metabolic processes. The energy in ATP is stored as a high energy terminal phosphate bond which means the energy will release when the terminal phosphate bond will break.
As the terminal phosphate bond breaks the energy is released which is used by the cell to perform some metabolic activity. After this reaction, the ATP converts into ADP. So the correct answer is B.
Mycorrhizae are associations formed by fungi that grow on the roots of trees. These fungi penetrate into the roots of the trees. The trees produce energy through photosynthesis and share it with the fungi. The fungi act as decomposers, breaking down dead organic matter to provide nutrients for the trees to grow. What kind of a relationship is exhibited in this example? The fungi share a mutualistic association with the trees. The fungi are a parasite for trees. The fungi share a commensal association with the trees. The fungi are predators for the trees.
Answer: The fungi share a mutualistic association with the trees.
Mutualism is a relationship among two species, in which two species lives in close association with each other. In this relationship both the species are benefited.
The given situation, is an example of mutualistic association of the fungal species with the tree. This is because of the fact that the fungal species provides trees with nutrients after the process of decomposition, that are necessary for the growth of the trees. In return the fungal species obtains carbohydrates produced by photosynthesis from the roots of the trees. Therefore, both the species are benefited hence, it is a mutualistic association.

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply.
mitosis
diploid cells
two cell divisions
gametes
identical DNA
The right answer are : mitosis, diploid cells, and identical DNA.
The answers "two cel divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.
Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.

What are brown bears doing as a result of panting
Answer:
Maintaining body temperature by cooling down
Explanation:
Brown bears have adaptive strategies to lower down the body temperature during hot months. Under hot sunny day, their breath rate is increased with shallow breaths. This is called as panting. The shallow breaths allow the cooler air to circulate over the moist mouth surfaces and leads to lower down the body temperature.
