Toemas’s syndrome is a autosomal dominant disease, homozygous lethal, seen at a frequency of 1 in 10,000 cats. Felines with this
Anastaziya [24]

Answer: 50% or 25% according to the genotype of the male cat.

Explanation:

The female cat is unaffected, and since this is an autosomal dominant diease, it means this cat does not have any affected alleles. Thereby,<u> its genotype is aa</u>. This is because dominant alleles show their effect even if the organisms only has one copy of the allele. The male cat is affected with this syndrome <u>so its genotype is either AA or Aa</u>. For this disease to manifest itself, only one affected allele is needed. Although both alleles can be affected so the individual can be homozygous dominant or heterozygous.

To find this we have to do a punnett square. Here, we use the gametes produced by each individual. <u>Gametes are sex cells, egg or sperm, which only have one allele of each gene.</u>

Assuming that the cross is between aa and AA, the gametes produced by "aa" are "a", and the gametes produced by "AA" are "A" So we are having a cross between an "a" gamete and a "A" gamete. 100% of the offspring will be Aa so it is a heterozygous, which will develope this syndrome. And, males have one Y chromosome and one X chromosomes, thereby the chances of having a male kitten is 50%. Then, to conclude, there is a 50% chances of having a male kitten with this syndrome.

And, assuming that the cross is between aa and Aa, the gametes produced by "Aa" are "A" but also "a" So we are habing a cross between an "a" gamete and "A" or "a" gamete (See picture) In this example, there is a 50% chances of having a kitten with the syndrome, because only one genotype produced (Aa) has the affected allele. And, as we said before, since there is a 50% chances of having a male kitten, we can said that there is a 25% chances of having an affected male. Because to calculate both probabilities so that they occur simultaneously, it is necessary to multiply them. That is, 0.5 x 0.5 = 0.25 x 100 = 25%.

Which statements about kinetic energy are true? It's always transformed into potential energy. It's always associated with motio
Fittoniya [83]

Answer:

It's always associated with motion

It can be transferred from one object or body to another

Explanation:

Kinetic energy is the energy due to motion of a body.

  • Moving objects possess kinetic energy which is resident in that body.
  • As with other forms of energy, it can be transferred from one body to another.
  • Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc..
  • As a body moves, the kinetic energy is increases.

Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from ov
ValentinkaMS [17]

Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.

Explanation:

Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.

According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.

Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)
Over [174]

Answer:

a. The letters Na with one dot

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.

A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.

Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.

For example, the Lewis structure diagram for Sodium (Na) is •Na.
