Henry puts a plant into a beaker with water. After sometime he added blue ink into it A few hours later he observes that flowers turn from white to blue.

Answers

Answer:

The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.

Explanation:

Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.

if a child had O type blood and the mother had B type blood and the father had A type blood, could a blood test eliminate the father

Answers

Answer:

No, a blood test could not eliminate the father.

Explanation:

The mother had B type blood, so the possible genotypes are BB and BI.  The father had A type blood, so the possible genotypes are AA and AI.  The child had O type blood, so the only possible genotype is II.  If the mother has the genotype BI and the father has the genotype AI, then there is a 25% chance the child will have the blood type O, or II (I used a punnet square with the genotypes BI and AI to solve this.)

What are the Amino acids of the mutated DNA sequence: TAC ATC TTG GCG ACG ACT

Answers

Answer:

Tyr Ile Leu Ala Thr Thr

Explanation:

In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of  20 amino acids and these amino acids are coded by a pair of three bases.  

There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).

The given mutated DNA sequence will also code for some amino acid, that is as follows:

TAC - Tyr (Tyrosine)

ATC - Ile (Isoleucine)

TTG -  Leu (Leucine)

GCG - Ala (Alanine)

ACG - Thr (Threonine)

ACT - Thr (Threonine)

Thus, The mutated DNA sequence  TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.

What makes plant material more difficult to digest?

Cell walls can make plant material difficult to digest. Many herbivorous mammals have wide molars. These big teeth help them grind up leaves and grasses.

Which of the following explains why an apple looks red? The apple reflects red light and absorbs all other visible wavelengths. The apple absorbs red light, and reflects all other colors of light.. The apple is absorbs all visible wavelengths, but absorbs red light better The apple is reflects all light that hits its surface.​

Answers

Answer:

The apple reflects red light and absorbs all other visible wavelengths

Explanation:

The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)

The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.

What is Absorption and reflection of light?

Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.

Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.

Therefore, the correct option is A.

What will happen to the parts of the cricket as it travels through the digestive system?

Are there any concerns about certain people consuming crickets?

Answers

Answer:

it would be broken down

Explanation:

the digestive systems purpose is to break down food into energy

As the food goes from the very first part of the digestive system it reaches the last part as in its most digested form. The situation is possible because of the digestion.

What is the very first organ of digestive system ?

It is the mouth that is solely making enough of digestion as it contains the amylase which is responsible for the digestion of starch.

As the food reaches the mouth it gets mixed with saliva which makes it easier to get break into and the food in this condition is called as bolus where the food will enter into the esophagus that is the food pipe via the peristalsis where the inward and outward movement of food pipe makes it enter the stomach.

In stomach the process of churning takes place where it gets mixed with the digestive juices and the food mixing with the digestive juices breaks into its simpler constituents.

how can patterns be used to identify common ancestry?

Answers

Answer:

5

Explanation:

4

......"...................."

By comparing and contrasting morphological or genetic traits of an organism, patterns can be used to determine its common ancestry. When species exhibit comparable traits, it shows that those traits were inherited from a common ancestor. On the other hand, when organisms exhibit different characteristics, it implies that they diverged from a common ancestor and evolved separately.

What are patterns used in common ancestry?

In genetics, common ancestry can be determined using patterns in DNA sequences or protein structures. A high degree of similarity between the DNA or protein sequences of two or more species indicates a tight relationship and a more recent common ancestor.

In contrast, different DNA or protein sequences within species indicate a more distant common ancestor and a more distant relationship between them. Scientists can reconstruct the evolutionary history of many animals and find patterns of common ancestry by comparing the DNA sequences of those organisms.

Therefore, by comparing and contrasting morphological or genetic traits of an organism, patterns can be used to determine its common ancestry.
