how many bacteria cells are produced at time T4 ?

Answers

Answer:

256.

Explanation:

If a bacterium divides once in every half an hour, it means it will double in half an hour. Hence a number of the bacterium after half an hour will be 1×2=2. After one hour the number of bacterium will be 2×2=4. Similarly, it one and a half hours it will be 4×2=8. In two hours it will be 8×2=16 in two and half hours, it will be 16×2=32. In three hours it will be 32×2=64. In three and half hours it will be 64×2=128. Hence, in 4 (four) hours the number of bacterium will be 128×2=256.

How many genders are there?

Answers

Answer:

Nobody really knows how many genders there are.

Explanation:

It widely depends whether you're referring to actual genders or gender identity types. Even then, though, there is not a definite or limited amount of either. For more clarification about the differences...

Gender identity types include: transgender, nonbinary, agender, demigender, etc.

These are not genders because they don't specify what you identify as, they are simply stating that you do not identify with your sex at birth. Don't call these genders, because that would be putting agender and nonbinary people into a binary.

Actual genders include: two-spirit, pangender, polygender, etc.

These are GENDERS rather than gender identity types because they somewhat specify what you identify as.

To say that there are only two genders is incorrect, as gender is a social construct. That does not mean it's useless, it just means that it wasn't constructed correctly because nobody knows for a fact how many genders and gender identity types there are and we probably never will because it's based on one's individual feelings.

Answer:

alot. if you are talking about what you are born with (sex) then there is 3. which is male, female, and intersex. GENDER is completely different. there is too many that i can even say but you can be a girl, a boy, somewhere on the non-binary spectrum (non-binary, demigender, agender, gender fluid, ect), ect.

A. electrons
B. oxygen
C. pigments
D. ATP​

Answers

Answer:

A. electrons

Explanation:

Energy in form of ATP is generated at both cellular respiration and photosynthesis. In cellular respiration, energy (ATP) is synthesized in the mitochondria when ELECTRONS (e-) passes through series of complexes composed of proteins called ELECTRON TRANSPORT CHAIN.

On the other hand, ATP is synthesized when ELECTRONS produced from splitting water i.e photolysis of water, passes through photosystems 1&2 in the chloroplast (thylakoid).

Answer: Electrons

Explanation: The electron transport chain is a series of molecules that accept or donate electrons easily

Mendel worked with pea plants, which are usually (cross-pollinating / self-pollinating). When he transferred pollen from one pea plant to another, he was (cross-pollinating / self-pollinating) the pea plants to (fertilize / segregate) the eggs and form embryos within a seed.

Answers

Answer:

1. self-pollinating

2. cross-pollinating

3. fertilize

Explanation:

Gregor Mendel was an Austrian monk regarded as the Father of Genetics due to his immense contribution to discovering the patterns of inheritance. During his lifetime, Mendel worked with garden pea plants (Pisium sativum). One of the notable reasons he worked with peas is their ability to SELF-POLLINATE.

However, Mendel transferred pollen from one pea plant to another in a process called CROSS-POLLINATION. In cross-pollination, the pollen from one plant is transferred to another plant in order to FERTILIZE the egg and form embryos within a seed.

Answers

Answer:

Adaptation.

Explanation:

Adaptation occurs when the acid tolerance of several plant species has increased significantly in the polluted area. The main reason for this tolerance is the change in the genetic makeup or mutation occurs in the cell due to the exposure of DNA to the chemicals of the environment that cause pollution. The plant adopt the environment by producing certain chemicals that cancel the effects of pollutants and as a result, the plant survive.

The resting potential of resting neuron is caused by ________.A.A higher concentration of Na+ on the outside of the cell making it more positive outside.B.A higher concentration of Na+ on the inside of the cell making it more positive inside.C.A higher concentration of K+ on the outside of the cell making it more negative outside.D.A higher concentration of K+ on the inside of the cell making it more positive inside.

Answers

The resting potential of a resting neuron is caused by a higher concentration of Na+ on the outside of the cell making it more positive outside. So, it's A.

What do you mean by Resting potential?

Resting potential may be defined as a condition of the imbalance of electrical charge that exists between the interior of electrically agitated neurons and their surroundings.

During resting potential, the passive efflux of K+ ion is more than the influx of Na+ ions. This imbalance makes the inside of the cell more negative as compared to the outside.

Therefore, the correct option for this question is A.
