Answer:

The probability of two healthy Tay-Sachs carriers having a child that has the disease will be [tex]25[/tex] %

Explanation:

It is given that Tay Sachs is a recessive disorder which means the genotype must both recessive allele.

Let the dominant normal allele be T and the recessive diseased allele be t

Genotype of a healthy Tay-Sachs carriers will be Tt

Tt * Tt

TT, Tt, Tt, tt

Only child with genotype tt will have Tay-Sachs disease

Hence the probability of two healthy Tay-Sachs carriers having a child that has the disease will be [tex]\frac{1}{4} * 100 = 25[/tex] %

Answer:

B each new layer has a new bit of the story to tell and you can see sequential time with each strata

A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.

2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA

D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals

C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Explanation:

Answer:

Though humans and mouse looks very different from each other but they have lot of similarity in their genes.

If a mouse is injected with human genes, it tell that how the DNA structure in mouse and humans are similar and genes carry out related functions.

When the human gene will inject into mouse, if the genes functions properly and do not show any alteration in function, it means DNA structure is similar in both organisms.

Recessive Allele - Small Letter

Explanation:

Answer:

The estrogen level decreases during the ovulatory phase, and the progesterone level starts to increase. And it is important, because hormones that are being releazed stimulates the egg to move from the fallopian tube, which then leads to menstruation.

Explanation:

The ovulatory phase begins with a surge in luteinizing hormone and follicle-stimulating hormone levels. Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins.

Answer:

Hormone levels generally decrease.

Explanation:

Change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.

Water cycle is the continuous movement of water between Earth and atmosphere. It is also known as Hydrological cycle. Water Cycle occurs in three phases i.e. Solid , Liquid and Gas. This cycle never stops, it doesn't have a beginning or an end. It's like a big circle.

Liquid water evaporates into water vapour which condense to form cloud and precipitates back to earth in the form of rain or snow. It is a simple circular cycle of evaporation, condensation and precipitation.

Water vapour is the primary form of atmospheric moisture. Its storage is small, water vapour is extremely important in forming the moisture supply for dew, frost, fog,etc.

There are Five parts of the water cycle. They are

1. Evaporation

2. Transpiration

3. Condensation

4. Precipitation

5. Runoff.

Thus, change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.

Explanation:

Answer:

The size of the crystals in granite will be different from the size of the crystals in basalt depending on how they are formed and how they are cooled which determines the nature of the crystals they produce. Granite takes a much longer time to form than basalt because granite takes a very long time to cool down since it is intrusive giving minerals to be well-formed and producing a bigger size of crystals with individual mineral grains that are can be seen without the need for bigger magnification. While basalt crystals are much smaller as the crystals form very quickly because the magma comes out of the earth and cools quickly giving rise to fine-grained minerals.

Explanation:

Granite and basalt are both igneous rocks.

Granite takes a longer time to cool as it hardens under the earth's surface causing the delay in cooling while basalt takes a shorter time to cool as it hardens above the earth's surface.

Answer is Archaebacteria

Explanation:

Answer:

The correct answer is - option C.

Explanation:

In this statement, he explained that there are 40 organisms that are comprised in the 3 species,1 phylum, and 2 kingdoms. It is not accurate as one phylum can not be placed in two distinct kingdoms.

A single phylum can have more than one species and one species also have hundreds and thousands of organisms. The phylum is lower taxa than the kingdom in taxanomy.

Answer:

Explanation:

The reason why insects are so successful in diversifying and adapting to different environments is closely related to their morphological and physiological adaptations.

In general, and compared with other groups, insects are small-sized. This characteristic also turns to be important and advantageous. Being small helps them find refuge in any place, escaping from predators, and as they are small they do not need too much food to survive.

Insects have a light and resistant exoskeleton made of chitin, a nitrogenated polysaccharide. This structure turns to be very important because it is impermeable to water, which helps the insect to avoid dehydration, helping the invertebrate to inhabit many different kinds of habitats. Also, the exoskeleton protects the arthropod from toxic substances and their natural enemies attacks, such as predators and pathogens

Insects are the only invertebrate with wings. Flying capacity is probably the most important adaptation that helped insects in their dispersion process to new areas. Being able to fly allows them to move huge distances looking for food, refuge, or mate. However, during evolution, some groups have lost the wings or have reduced their flying capacity.

The short life cycles, and their numerous litters, also helped them in their diversifying process.

Answer:

Los iones K + tienen un gran efecto en la apertura de los estomas.

Explicación:

Existe una gran relación entre la concentración de iones K + dentro de las células de guarda y la apertura de los estomas porque la concentración de iones de K + aumenta la concentración osmótica dentro de la guarda. El agua entra en las células de guarda por endosmosis, lo que aumenta la turgencia. La presión de turgencia de las células protectoras aumenta debido a esta endosmosis y las células protectoras permiten que los estomas se abran, por lo que podemos decir que los iones K + tienen un gran efecto sobre la apertura de los estomas.

The student can do a couple of things to make sure that the heat from the lamp did not affect the rate of photosynthesis. These include:
