Which approach would be least helpful in determining genetic differences between species?

Answers

Answer 1

Answer:

the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff

Explanation:

Answer 2

Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.

What is an example of this ?

For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.

In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.

This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.

Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

The Canadian lynx and the snowshoe hare have a predator-prey relationship. You will use two sets of population data and present them in a single graph.


Using the second picture below,label the x-axis ‘‘Year of Study’’.Label the x-axis with data listed in the first picture.(pls make sure that the grid your using is same as picture two below)


Based on the sizes of the numbers for each population, create a scale on the two separate y-axes. The snowshoe hare population ranges in size from 5000 to 95000. Label the y-axis on the left side of the x-axis as “Hare population (in thousands)." Number this y-axis from 0 to 100, in intervals of 10. The lynx population ranges in size from 500 to 6000. Label the y-axis on the right side of the x-axis as "Lynx population (in thousands)." Number this y-axis from 0 to 10, in intervals of 1.

what is made when a sperm cell combines with the polar nuclei?

Answers

Answer:

Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).

Answer:

endosperm

Explanation:

The second fertilization results in the endosperm, which is a special tissue used to nourish the embryo.

Have both clockwise and anticlockwise directions and warmer temperature.

Explanation:

Atlantic oceans have a circular pattern of surface currents that moves in the clockwise direction in the Northern Hemisphere and counterclockwise direction in the Southern Hemisphere while on the other hand, the temperature of the Atlantic basin is warm and having high salinity in the water. The Atlantic Ocean has about 9 degrees Celsius more warmer than the water of Pacific Ocean that leads to the warmer climate of Atlantic basins.

Jayden wants to model the hydrological cycle. He puts some water in a small plastic cup, draws a line on the cup at the water level, and places the cup upright on a window sill. After three days of being undisturbed, the amount of water in the cup is below the line Jayden drew. This is an example of:

A. Transpiration
B. Evaporation
C. Condensation

evaporation...evaporation occurs when it is warmer and the particles get further apart so they kinda drift off and go their own way(they turn into a gas) then the water in the cup has a less amount so that is why the water is below the line

v-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins but are otherwise catalytically inactive. What do you think is the effect of v-FLIP expression in the host cell?A. It promotes apoptosis mainly via the extrinsic pathway.B. It inhibits the extrinsic pathway of apoptosis.C. It activates only the mitochondrial pathway of apoptosis.D. It inhibits the intrinsic pathway of apoptosis.E. It enhances the caspase cascades in both the intrinsic and extrinsic pathways.

Answers

Answer:

B. It inhibits the extrinsic pathway of apoptosis

Explanation:

Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
