which type of drosophila probably changed the least over time?

Answers

The type of Drosophila that probably changed the least over time is the Drosophila melanogaster.

What do you mean by Drosophila?

A Drosophila may be defined as a fruit fly that serves as one of the most important model organisms in the field of biological sciences due to its large chromosomes, high reproduction rate, and various varieties.

As compared to Drosophila willistoni, Drosophila equinoxialis, Drosophila equinoxialis caribbensis, etc. Drosophila melanogaster changed very least over time after analyzing its evolutionary pathway.

It is because it may consist of a large chromosome but a simple arrangement of genes, its well-specified segment polarity genes, pair-rule genes, and maternal effect genes.

Apart from this, it may also be because of less natural selection applied to Drosophila melanogaster.

Therefore, the type of Drosophila that probably changed the least over time is the Drosophila melanogaster.

why do cells need to regulate what goes in and out of them?

Answers

my Answer:

These molecules are essential for living things. The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through

Like the camel, many animals that live in soft sandy areas have large wide feet compared to their body size. The
large feet are an advantage in these environments because they -
are rapidly toughened by sharp sand grains
distribute body weight over a large area
allow rapid digging in the sand
Dreduce the vibrations caused by walking

Answers

Answer:

distribute body weight over a large area

Explanation:

This one's fairly simple. If you have large feet, then your body weight is distributed over a large area (you don't sink as much in sand). If your toes were small, massive body weight would sink the feet into sand.

Why do baby bones contain more cartilage than an adult's?

Answers

Babies are less bony for a good reason; if they were fully “hardened”, it would make delivery almost impossible. Infants’ bodies need to be extremely soft and limber so that they can be born in the first place! Babies are born with more cartilage (than bone), but it gradually turns into bone over a period of time through a process called endochondral ossification. This is a vital part of the developmental stages of a fetus and leads to the creation of bone tissue in the body. As the baby grows, cartilage is replaced by bone matrices. Calcium salts (that babies get from their diet) are laid to form hardened bones. This is the reason why adults have fewer bones than babies because, for babies, many small bony segments fuse together to form a single bone.

STIMULUS – RESPONSE PERFORMANCE LAB 38 points

PURPOSE: To measure response time after visual, auditory, and tactile stimuli have been practiced.
MATERIALS: meter stick or a yard stick (If you don’t have one - something about three feet long and stiff will work. You could get cardboard for example and mark off the distances on it..)




PROCEDURE:

Place your arm on a desk or table top with your hand resting on the edge. Your thumb and forefinger need to be projecting over the edge and about 2cm apart.
Your LC, friend or family member will hold the meter stick in a vertical position so that the zero end of the meter stick is halfway between your thumb and forefinger. The holder of the stick will drop it without warning you. You are to catch the meter stick as soon as possible after it has been released. Record on the data table the number of centimeters the meter stick dropped before you caught it.
Repeat the procedure 9 more times.
Repeat the procedure in steps 2 and 3 but this time close your eyes and have your LC, friend or family member tell you the moment the meter stick is dropped. Repeat this 9 more times and record the data in the data table.
Repeat the procedure in steps 2 and 3 but this time use a tactile stimulus. Have your LC, friend or family member touch you as soon as the meter stick is dropped. Be sure your eyes are closed. Repeat 9 more times and record your data.
Repeat the procedure in steps 2 and 3 but this time your LC, friend or family member will try to distract you as they drop the meter stick. Repeat 9 more times and record your data. 20 pts

how is climate change a feedback loop ?

Answers

Answer:

tbh i dont even know

Explanation:

Answer:

Global warming itself isn’t a feedback loop, it is caused by radiative forcing an induced response to the emission of greenhouse gases by humans. There are both positive and negative feedback loops that exist in global warming and climate change. Overall studies show the climate temperature response is higher than that implied by radiative forcing response of the emissions alone - so that means that the “positive” (reinforcing) feedbacks are dominating. Although many feedbacks are already in play there are some big potential reinforcing feedbacks that haven’t really started yet, so we have that to look forward to!

Select the correct answer from each drop-down menu. when a cat drops from a tree to the ground, the conversion of takes place. then cat runs up behind a mouse to obtain its food. after eating its prey, the conversion of takes place inside the cat’s body.

Answers

The correct answer from each drop-down menu is gravitational force, potential energy to kinetic energy, and then conversion of chemical energy to mechanical energy take place in this order.

What are the forms of energy conservation?

During the energy transformation steps, when there is no frictional dissipation, we say that energy is conserved. That is, all potential energy is transformed into kinetic energy, and vice versa. The sum of the kinetic and potential energies of a system is called mechanics.

In this case, When a cat drops from a tree to the ground follows the gravitational force, while the conversion of up behind a mouse to obtain its food is the process of converting potential energy to kinetic energy. And at last, after eating its prey, the conversion inside the cat's body takes place the chemical energy to mechanical energy.

What happens to the distance between molecules when a substance changes from a liquid to a gas? Why?

Answers

When a substance changes from a liquid to a gas, the distance between molecules increases.

Explanation:

The distance between molecules increase because vaporization occurs. During the process of vaporization, the liquid molecules acquire higher kinetic energy, which means they move more quickly and freely through the substance.

Which of the two sequences of rocks, a-d and e-g, was disturbed by crustal movements after its deposition?

Answers

Answer:

Sequence A-D was disturb by crustal movement after it was deposition. We have evidence in given cross section that sequence A-D was disturb by crystal movement just see above this sequence there is conglomerate bed which indicates it is uncomformity and that below uncomformity plane all beds are inclined so it clear evidence that sequence A-D got disturbance by crustal movement.

Explanation:

Sequence order and principal are given below.

one can order the event in any given cross section on the basis of apply some principal like order of super position, principal of cross cutting relationship, principal of inclusion, principal of original horizontality etc. Order of superposition tell us that if rock is undeformed then older rock would be at bottom and younger at top, principal of cross cutting relationship tell if some igneous body intruded in some rock layer so it mean that layer is older than age of intrusion.
