How can we tell that two species shared a common ancestor, and are therefore related?
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules
Explanation:
There are multiple ways you can tell
you can look at the bone structure of an organism and see if it's homolougous
Or use a cladogram to tell what species share a common ancestor ( hope this helps)
The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?
Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.
Answer:
earthquakes occur when the edges suddenly become unstuck and slip along a fault

Which of the following substances is/are involved in
oxidative phosphorylation of cellular respiration?
Answer:
the answer will be
ADP
Oxygen
ATP
so its all the above
Explanation:
The substances involved in oxidative phosphorylation are the electron transport chain, oxygen, and ATP synthase.
The substances involved in oxidative phosphorylation of cellular respiration are:
Electron transport chain: It consists of a series of protein complexes located in the inner mitochondrial membrane. Electrons from carrier molecules, such as NADH and FADH2, are passed along the electron transport chain, resulting in the generation of a proton gradient.
Oxygen (O2): Oxygen acts as the final electron acceptor at the end of the electron transport chain. It combines with hydrogen ions to form water (H2O).
ATP synthase: This enzyme is located in the inner mitochondrial membrane and utilizes the energy from the proton gradient to generate ATP through the process of chemiosmosis.

A dam is built across a river to generate electricity. What is likely effect of the construction of a dam on the river?
a)increase in the size of fish in the river
b)increase in the water flow in the river
c)decrease in the population of aquatic organisms in the river
d)decrease in the amount of pollutants dumped into the river
Answer:
c i think
Explanation:
Most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.
What is Population?A Population may be defined as the group of individuals significantly belonging to the same species living in the same area in a definite time period.
When a dam is built across a river in order to generate electricity, it results in the reduction of the population of aquatic organisms in the river.
This is because the whole construction affects the natural habitat of aquatic organisms as well as their adaptations. So, such populations are frightened due to external construction and do not play their essential roles.
Therefore, most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.

A cell has undergone determination to become an epithelial lung cell. If it is transplanted to a leg muscle, what do you think will happen to this cell?
Answer:
Change occur in form and structure of the cell.
Explanation:
The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.

Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.
Which of the following are sites where waste products are released from the body but not where they are produced
O skin and anus
O large intestine and small intestine
O liver and kidney
O tubules and ureters
Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.

A rabbit is born with brown(g) fur. It has 9 other siblings from the same
litter, and they all have white(G) fur.
Select the True Statements.
• Brown fur is caused by a mutation
•The dominant allele is G
•The dominant allele is g
•gG is a genotype for white fur
•Brown fur is the recessive trait
•Gg is a genotype for brown fur
•The recessive allele is g
•White fur is dominant over brown fur
Answer and Explanation:
What we know:
1 rabbit born with brown fur (g).
9 other siblings with white fur (G).
The correct answers:
- The dominant allele is G
This is because G is capitalized, and there are more white bunnies than brown.- Brown fur is the recessive trait
We see that (g) isn't capitalized for the brown bunny, and that there was only 1 brown bunny out of the 10 bunnies in total. So, brown fur is a recessive trait.- The recessive allele is g
This is correct because g isn't capitalized, and acts recessive, or doesn't appear unless the genotype is gg, in which the recessive trait will then appear/unhide.- White fur is dominant over brown fur
There is more white fur bunnies than brown fur bunnies, so the white fur trait is dominating the brown fur trait.I hope this helps!

How do mountains affect the climate of a region?
(giving brainlist)
Answer:
As context, there are two sides of a mountain range:
A) The windward side
B) The leeward side
As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.
In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.
This is why you see mountain ranges near deserts.
What might happen to a desert biome if the area received more rain than it normally receives over an extended period of time? Describe some of the changes that you might expect to see
Answer:
Desert biome will change.
Explanation:
Desert biome will change if the area received more rain than normal it receives over an long period of time because the vegetation on that area appears. The change in rainfall pattern in the desert area changes the animals present in this region because the temperature of the desert is no longer suitable for the desert animals so they migrated and other organisms come to this place.
