how does a beneficial trait increases an organism's survival and potential reproductive success.

Answers

Answer:

This cumbersome trait significantly decreases the male's chances of survival. ... natural selection: that is, that organisms better adapted to their environment would benefit from ... the individual's reproductive success, even at the expense of their survival (Darwin 1871). ... A successful male can potentially sire many offspring.

Explanation:

The beneficial trait increase the survival and potential reproductive success of the organism as they help organism to thrive in their unfavorable changing environment.

Natural selectionThe natural selection can be defined as the differential survival and reproduction of those organisms which have beneficial traits over others.For example, the color change in chameleon helps them to remain undetected from predator population as well as from prey so it helps in increase in rate of survival of chameleon also helps them to reproduce and increase in number.

Hence, beneficial traits increase the rate of survival and reproduction of organisms.

You might then also realize that the new method, at least on paper, may have additional applications. ... which makes the technology attractive to yet more scientists.

Explanation:

Hoped I helped you out please mark me brainliest!!!

With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.

What is a microscope?

A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.

In most cases, the light is focused on the sample by passing it through a condenser.

After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.

The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.

Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

What is the major difference during cytokinesis in eukaryotes with or without a cell wall?

Answers

Answer:

Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.

Explanation:

Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.

The major difference during cytokinesis in eukaryotes with or without a cell

wall is in the formation of cell plate in cells with cell wall while in animal

cells cytokinesis occurs through the formation of a cleavage furrow.

Cytokinesis is the process of cell division in which the cytoplasm divides

into two. Plants have cell walls while animals lack cell walls.

Animal and plant cells form cleavage furrow and cell plate respectively

which aids division into two equal parts.

In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens

Answers

Answer:

seminiferous tubules

Explanation:

Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.

What is the process of Asexual reproduction? Honey Bees

And
What is the process of Sexual reproduction? Honey Bees

Answers

Answer:

ASEXUAL

female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees.  The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.

SEXUAL

The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?

Answers

Answer: The percent increase in the mass of cylinder of beetroot is 8%.

Explanation:

To calculate the percent increase in the mass of cylinder, we use the equation:

[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]

We are given:

Final mass of the cylinder = 2.7 g

Initial mass of the cylinder = 2.5 g

Putting values in above equation, we get:

[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]

Hence, the percent increase in the mass of cylinder of beetroot is 8%.
