Viruses are able to invade cells after first attaching to their Cell membrane.

What are viruses?

A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA). A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself.

A virus frequently causes harm to the host organism by killing the host cell in the process. AIDS, COVID-19, measles, and smallpox are well-known examples of viruses that cause human disease.

Viruses can infect people. But in reality, viruses infect a wide variety of organisms. For example, there are viruses that infect fungi and viruses that infect bacteria.

Therefore, Viruses are able to invade cells after first attaching to their Cell membrane.

A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase

Answers

Answer:

D. G2 phase and M phase

Explanation:

If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?
ATP - decrease, stay the same, increase
NADPH - decrease, stay the same, increase
sugars - decrease, stay the same, increase

Answers

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

Explanation:

Photosynthesis is a type of biosynthesis that produces glucose from the reactants: sunlight, carbon dioxide, and water. It occurs in the chloroplast in two phases, the light-dependent, and light-independent/dark reactions where sugars are made. Pigments like chlorophyll absorb light energy at specific wavelengths in the light reaction which activates photosystems

Here:

chlorophyll forms photosystems (PS I & PSII) with proteins called a complexPS II absorbs and transfers light energy to the reaction core. a water molecule is split apart to form an electron, H+ and oxygenElectrons are shifted to photosystem I from photosystem II.  ATP and inorganic phosphate are synthesized from ADP.  H+ is added to NADP to form NADPH

The NADPH is integral to the Calvin Cycle, as part of the light independent reactions- these synthesize sugar molecules.

If PS II no longer works,  there will be less ATP, NADPH, and no sugars produced.

What would happen to the concentrations of ATP, NADPH and Sugars if Photosystem II (PSII) stopped working is a: decrease.

During photosynthesis, the primary acceptor of carbon are Photosystem I (PSI) and Photosystem II (PSII) because it occurs in a light-dependent reaction.

Photosystem II (P680) is a large membrane protein complex which serves as a primary acceptor of carbon during a light-dependent reaction.

However, the following would happen when the Photosystem II (P680) stops working:

A decrease in the concentrations of ATP.A decrease in the concentrations of NADPH.A decrease in the concentrations of Sugars.

Can carbon atoms bond with other atoms to form long chains?

Answers

Answer:

yes

Explanation:

Answer:

The Uniqueness of Carbon

Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms.

Explanation:

Discuss some of the advantages to having a cycle that partially replenishes itself. In the Calvin cycle, what would happen to the cycle if there was no carbon dioxide available?

Answers

Answer:

The carbon atoms used to build carbohydrate molecules come from carbon dioxide, the gas that we exhale with each breath.

Explanation:

Dark reactions are also referred as "light independent reactions" (since they can occur during day or night) or as "carbon-fixation" (since carbon dioxide is taken from the air and carbon is affixed to compounds in the plant) or as the Calvin Cycle (named for the person who discovered it).

Although every zebra has a unique pattern of black and white stripes, the differences are very subtle. The main evolutionary advantage of the stripes is the protection they provide against lions, the main predators of zebras on the African plains. When a zebra herd is packed together, a lion cannot distinguish individual zebras from one another, making it difficult to attack them.

Hi, you've asked an unclear question. However, I inferred you likely need affirmation whether the statement made is true.

Answer:

True

Explanation:

Indeed, zoologists have discovered that stripes on Zebras play an important role in preventing predators from attacking them. It is believed that their unique pattern of black and white stripes acts as a camouflage making them difficult to be spotted by predators.

Despite these findings, scientists are still researching reasons for such observations and they hope to find real-world applications of this natural design.

6. Blue

7. Long

8. Long

9. Short

Explanation:

Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.

Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.

Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.

For recessive long tails, tt gives short tails, TT and Tt gibe long tails

The following four ears of corn were taken from separate plants. Each kernel represents an offspring. The kernels on the four ears were counted for the color trait (purple or white) and/or sweetness trait (starchy or sweet). The data gave these phenotypic ratios for the four ears:

Ear #1 – 3 purple : 1 white
Ear #2 – 3 starchy : 1 sweet
Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Ear #4 – 1 purple : 1 white

Which traits are recessive?

Answers

Answer:

the answer is white and sweet, i just took the quiz

Explanation:

The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.

-------------------------------

By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.

Let us assume two diallelic genes, each coding for one trait.

Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.

When we are only considering one single gene,

the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.

the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.

When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1

9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.

Now let us analyze each Ear,

Ear #1 – 3 purple : 1 white

Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white

Ear #2 – 3 starchy : 1 sweet

Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweet

Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet

Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweet

Ear #4 – 1 purple : 1 white

Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: White

The recessive traits are white color and sweet taste.
