I haven't heard of heavy metal exposure causing nervous system damage, but I have heard that when you inhale during mining, you are inhaling all different particles and dust which causes other respiratory diseases, such as chronic obstructive pulmonary disease. Noise pollution is definitely true as people have lost their hearing from all the noise underground which also caused headaches. This is my opinion, sorry that I'm late!

Which of the following most accurately describes most scientists' current understanding of the evolution of humans?
A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.

Answers

Answer:

B: Humans, chimpanzees, and other primates share a common ancestor.

Explanation:

According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.

Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
O density dependent
O density independent
O population dependent
O population independent

Answers

Answer:

Density independent is the correct answer

The type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

What are density-independent factors?

Density-independent factors are environmental factors that affect populations regardless of their size or density. These factors can include natural disasters such as forest fires, floods, hurricanes, droughts, and other extreme weather events. Other examples of density-independent factors include habitat destruction, pollution, and climate change. In the scenario described, a forest fire destroyed an area, which can lead to the decline of both tree and bird populations. The fire could kill the trees and destroy their habitats, making it difficult for the surviving trees to grow or reproduce.

Hence, the type of limiting factor that causes this scenario are density-independent factors, which is Option B, because they affect populations regardless of their size or density.

what formed the alps mountains

Answers

Answer:

The Alps arose as a result of the collision of the African and European tectonic plates, in which the western part of the Tethys Ocean, that was formerly in between these continents, disappeared.

Answer:

The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn.

Investigators interested in studying the activation of apoptosis inject cytochrome c into the cytosol of two types of mammalian cells: cells that are normal and cells in which Bak and Bax have been inactivated by mutation. How would these cells be predicted to respond? Question 3 options: The normal cells will undergo apoptosis and the mutant cells will continue to grow. The mutant cells will undergo apoptosis and the normal cells will continue to grow. Neither cell type will undergo apoptosis, so both will continue to grow. The normal cells will undergo apoptosis and the mutant cells will die by necrosis. Both cell types will undergo apoptosis.

Answers

Answer: Both cell types will undergo aptosis

Explanation:

cells lacking both Bax and Bak, but not cells lacking only one of these components, are completely resistant to tBID-induced cytochrome c release and apoptosis. Moreover, doubly deficient cells are resistant to multiple apoptotic stimuli that act through disruption of mitochondrial function: staurosporine, ultraviolet radiation, growth factor deprivation, etoposide, and the endoplasmic reticulum stress stimuli thapsigargin and tunicamycin. Thus, activation of a “multidomain” proapoptotic member, BAX or BAK, appears to be an essential gateway to mitochondrial dysfunction required for cell death in response to diverse stimuli.


Which factor can decrease the rate of a chemical reaction?

Answers

The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.

What is digestion?

Digestion is the process whereby ingested food is converted into substances that can be utilized by the body.

Digestion involves the breakdown of large molecules of chemical substances in food into simpler molecules that can be absorbed.

Enzymes are responsible for the chemical degradation of food substances. A specific enzyme in charge of breaking down starch is called amylase and it is present in the saliva of the mouth.

An astronomer measures the distance to two stars using the parallax method. When comparing the placement of the stars six months apart, the star that is further away: A. Changes position the most B. Changes position the least C. Appears brighter D. Appears dimmer

Answers

Answer:

I would say A but im not 100% sure

Explanation:

The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.

What is the parallax technique?

The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.

It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.

Therefore, the star located farthest will change its position the most.

A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the mutation?

Answers

Answer:

The sequence would be ATTCATTCA.

Explanation:

Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.

So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out. Trust me, it's a great video, it's much better than my explanation.

The frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.

What do you mean by Sonar?

The sonar may be defined as a device that is used to find the distance, direction, and speed of underwater objects like water hills, valleys, icebergs, submarines, sunken ships, etc.

The universal wave equation states that the velocity of a wave is equal to the products of its wavelength and frequency.

   v = λf

∴ f = v/λ

1500/0.032 = 46,875 Hz.

f = 4.6×[tex]10^4[/tex] Hz.

Therefore, the frequency of the pulse is 4.6×[tex]10^4[/tex], when the wavelength of the sonar pulse is 3.2cm. and has a speed of 1,500 m/s in water.
