How is cross pollination carried out in nature?
A, B, or C?

Answers

OPTION B is the correct answer

Cross-pollination is carried out by bees and other pollinators, which is present in option B, as cross-pollination is a process in which pollen from the male reproductive organs of a plant (such as the stamen) is transferred to the female reproductive organs.

Cross-pollination is facilitated by various agents, including insects, birds, wind, and even water. These agents inadvertently carry pollen from one plant to another as they move between flowers or plants. Insect pollinators, such as bees, butterflies, and beetles, are the most common and efficient carriers of pollen in cross-pollination. They visit flowers to obtain nectar or pollen as a food source, and in the process, pollen grains get attached to their bodies and are transported to other flowers.

6. The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles,
and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local
ecosystems?
A. The variety of interactions among the different species helps the ecosystems remain
sustainable.
B. The variety of interactions among the different species prevents the ecosystems from being
sustainable.
C. The uniformity of interactions among the different species prevents the ecosystems from
being sustainable.
D. The uniformity of interactions among the different species helps the ecosystems remain
sustainable.

Answers

Answer:

A.

Explanation:

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

An object has a mass of 26kg has a force of 19N applied to it.
What is the resulting acceleration of the object?
Show your work

Answers

Answer:

f=ma

so if we are finding acceleration, we divide force by mass to get the acceleration which can be 19/26 which gives 0.73 as resulting acceleration

Hope it helps

When an object has a mass of 26kg has a force of 19N applied to it then the resulting acceleration of the object would be 0.73 meters/second².

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum. The mathematical expression for Newton's second law is as follows,

F = ma

As given in the problem, when an object has a mass of 26kg has a force of 19N applied to it then we have to find the resulting acceleration of the object,

mass= 26 kilograms

force = 19 Newtons

Force = mass×acceleration

19 Newtons = 26 × acceleration

acceleration  = 19/26

                     = 0.73 meters/second²

Thus, the resultant acceleration of the object would be 0.73 meters/second².

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?

Answers

Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.

While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Answer:

If you mean the complementary strand of GAT: Answer is CTA

If you mean the strand for all of it (GATCCATGAGTTACG): Answer is CTAGGTACTCAATGC

Explanation:

Both strands always have to be in a sequence that pairs them to their nitrogenous base pair according to Chargaff's law. So always remember:

A pairs with T (Adenine with Thymine)

C pairs with G (Cytosine with Guanine)

Whenever you need to figure out the other strand, just switch the original base sequence with their base pairs to get the second strand/sequence.

The DNA structures of prokaryotic and eukaryotic cells share similarities and differences. One way in which they are the same is that
A. both have sugar-phosphate backbones
B most of the DNA is in the form of plasmids
C both have a singular circular chromosome
D the DNA is packaged into several linear pieces

Answers

One way in which the DNA structures of prokaryotic and eukaryotic cells are similar is that both have sugar-phosphate backbones.

The DNAs of all living organisms, be it prokaryotes or eukaryotes, are similar and consists of 3 major chemical groups:

5-carbon deoxyribose sugarsnitrogenous purine or pyrimidine basesphosphate group

The pentose deoxyribose sugar and the phosphate group form the backbone of the structure of DNA. The sugars are linked together by phosphodiester bonds formed between the carbon 4 of each sugar and the methyl group attached to the phosphate.
