write a note on profundal zone​

Answers

Answer 1

Answer:

Profundal zone is the deep water zone of any lentic water body i.e. lake or a pond where the light can no longer penetrate because it is located below the range of effective penetration of light mostly below the thermocline. The lack of light and oxygen determines the type of biological community living there

Answers

Answer:

Summary. Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.

Work backwards: if you find an offspring that is not genetically identical to its parent's organism, what type of reproduction created it? why?

Answers

Answer:

The organism was created via sexual reproduction.

Explanation:

If it were genetically identical to its parent, then that would've meant that it was created asexually. In sexual reproduction, the offspring's DNA is more or less a combination of both parents' DNA.

Brainliest to best answer . . . Spider plant has plantlets and all of the plantlets are identical to the parent plant.



A. Sexual Reproduction
B. Asexual Reproduction

Answers

Answer: Both.

Explanation: Plants produce both asexually and sexually. If they produce asexually, they will use mitosis to produce offsprings. Roots can rise up to new plants or they can propagate by budding or cutting. Like a plant's root can be attached to another plant; that energy from the plant that is attached will get it. If a plant produces sexually, it will grow seeds, and those seeds will turn into a fruit.

For stars in the main sequence, which color of stars tend to have higher absolute brightness? (2 points)

The HR diagram is shown with Absolute Brightness on the y axis from negative four to six and Surface Temperature on the x axis from 40,000 to 2,500 degrees Celsius. There are several dots plotted between four and six absolute brightness and 10,000 to 2,500 degrees Celsius labeled Supergiants. There are several dots plotted between 1.5 and three absolute brightness and 7,500 to 2,500 degrees Celsius labeled Giants. There are several dots plotted between negative four and negative two absolute brightness and 30,000 to 7,500 degrees Celsius labeled Dwarfs. Down the middle, there are several dots plotted diagonally from ordered pair 40,000 and five down to 2,500 and negative three labeled Main Sequence.

Answer:

Blue Stars

Explanation:

Hope this helps :)

Blue stars tend to have higher absolute brightness for stars in the main sequence.

What is absolute brightness?

Absolute brightness, also known as absolute magnitude, is a measure of the luminosity of a celestial object such as a star or planet, expressed as an apparent magnitude that the object would have if it were placed at a standard distance of 10 parsecs (32.6 light-years) away from Earth.

It is an objective measure of an object's intrinsic brightness, independent of its distance from Earth. Absolute brightness is a useful tool in astrophysics for comparing the luminosities of stars and determining the distance to remote stars and galaxies. It provides a standardized method of comparison, allowing scientists to study the evolution and distribution of stars and galaxies throughout the universe.

How would Darwin’s explanation of long necks in giraffes differ from Jean Baptiste Lamarck’s explanation of the same trait?

According to Darwin's theory, giraffes that happened to have slightly longer necks and limbs would have a better chance of securing food and thus be able to have more offspring -- the "select" who survive.

It is possible if 1 or both parents have the blue-eyed recessive allele

It works both ways.

B=Brown-Eyed Dominant Allele

b=Blue-Eyed Recessive Allele

Solution 1:

Bb x Bb

Using a Punnett Square (You can look up "Punnett Square calculator" online to find an example) you can find that there is a 25% chance for BB alleles in the offspring, 50% chance for Bb, and 25% chance for bb.

This shows it's possible for an offspring to have blue-eyes.

Solution 2:

BB x Bb

Using a Punnett Square you can find that there's a 50% chance for BB alleles in the offspring and a 50% chance for Bb.

This shows that it's possible for an offspring to have blue-eyes.

She took four slices of bread from the same loaf, sprayed each with the same amount of water, and sealed them inside plastic bags. She kept two slices on the kitchen counter for six days.

The Galapagos island has a variety of tortoises with different physical characteristics. Can a Domed tortoise survive that lives on Isabella survive on the Island of Espanola? Explain.

Answers

Explanation:

Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks.

Answer:

Probably not. This is because the islands at Galapagos islands are all diverse and the turtles that live on each island have characteristics that help them survive on their island and not any other island so if you were to move one of the turtles locations it probably wouldn't survive because it doesnt have the needed characteristics do survive.

Sensory neurons are the neurons that carry the signal or information of the stimulus which is activated first when you touch a sharp object, Interneurons are the neurons that are present in the brain and spinal cord when activated to send messages in response to the stimuli of touching the sharp object, motor neurons are the neurons is carry the response signals from the brain and spinal cord to the muscle as it cause you to pull your hand away from the sharp object

A.
The dependent variable does not change and the independent variable does change.

B.
The dependent variable does not change and the independent variable does not change.

C.
The dependent variable is the control and the independent variable is the result.

D.
The dependent variable changes due to the changes made to the independent variable.

Answers

D. The dependent variable will change based on the value of the independent variable

The dependent variable changes due to the changes made to the independent variable is the statement that best describes the difference between these variables. So, the correct option is D.

What do you mean by Variables?

Variables may be defined as those components whose values may be changed during the course of the experiments.

The variations in the dependent variable rely on the value of independent variables. According to the independent variable, the values of dependent variables are met.

Therefore, the dependent variable changes due to the changes made to the independent variable is the statement that best describes the difference between these variables. So, the correct option is D.
