Answer:

Explanation: yes would cause problems with the embryo because a sperm and egg have 23 chromosomes each half mom half dad.

The sperm cell and the egg cell contain 46 chromosomes each, 46 + 46 = 92; a developing embryo would not survive if it contained 92 chromosomes.

This process results in the restoration of the diploid state, the formation of a zygote through the process of egg activation, and the beginning of a series of mitotic divisions that leads to cell differentiation and embryo development.

When a sperm and a female act during sexual contact, an egg is created and implanted in the female's uterus, resulting in fertilization. The sperm enters the fallopian tube, passes through the ovum's zona pellucida layer, and fuses with the egg to create the zygote (fertilized egg).

Therefore, 46 chromosomes are found in each sperm and egg cell, for a total of 92 chromosomes. An embryo would not survive if it had 92 chromosomes.

When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.

Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow. 

This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.

Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.

Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

Answer:

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.

Natural selection is an evolutive force that favor beneficial alleles increasing their frequency. The correct option is C). variation, inheritance, speciation.

Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population. It results from the interaction between the individuals' phenotype and the environment, which determines gene destiny in space and time.

Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.      

Aptitude (or fitness)  is the contribution of each genotype to the next generation. It is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.

Natural selection can act favoring an allele or against it, according to how it affects the fitness of individuals.      

In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.

Natural selection also acts on variation caused by mutations. Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.

Hence, a mutation can cause variation. If this variation turns to be beneficial to the population and increases individuals' fitness, it is favored by natural selection.

New generations inherit these new variants increasing their frequency in the population.

According to the environment and the species distribution, these changes might lead to speciation.

The correct option is C) variation, inheritance, speciation

Answer:

Photosynthesis vs Cellular Respiration

Uses water <=> Gives off water

Uses carbon dioxide <=> Gives off carbon dioxide

Makes Glucose <=> Breaks down glucose

Gives off oxygen <=> Uses oxygen

Occurs only in light <=> Occurs all the time; does not need light

Takes in light energy <=> Releases light energy stored in glucose

Explanation:

Photosynthesis and Cellular Respiration are both biological processes. One is the reverse of the other.

Photosynthesis is an anabolic process while cellular respiration is a catabolic process. It implies that photosynthesis synthesis food by capturing energy while cellular respiration breaks down food and releases energy for cellular activities.

The two processes are important to keep each other going.

Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.

Photosynthesis uses light energy, carbon dioxide and gives off glucose, water, and oxygen as by-product while cellular respiration uses water and glucose, and gives off carbon dioxide, water and energy as by-products.

While photosynthesis occur in green plants in the presence of light, cellular respiration occurs at all times.
