Answer:
B
Explanation:
Environmental conditions were very different on either side of the river, and over time these two groups of rhinos evolved such different characteristics that scientists classified them as two different species. This is an example of homologous speciation.
What is homologous speciation?
Organs or skeletal components of animals and organisms that are homologous suggest a connection to a common ancestor because of their similarity.
The appearance and purpose of these structures need not be identical. Other mammals with tails include rats, cats, and monkeys. Mammals have flexible vertebrae in their tails, which act as an extension of their torsos.
Although their primary purpose is to fend off insects, tails can also provide a sense of equilibrium for more reclusive species like cats.
Therefore, Environmental conditions were very different on either side of the river, and over time these two groups of rhinos evolved such different characteristics that scientists classified them as two different species. This is an example of homologous speciation.

A gene exists in two different forms (A and a). With respect to the allele present, which type of gamete(s) can a homozygous recessive individual produce?
a
A
Aa
A and a
Answer:
a
Explanation:
in the words, 'homozygous recessive', the root 'homo' in 'homozygous' means 'same' so that means that a two different alleles can not come from this individual. the word 'recessive' when referring to alleles means it is the submissive (opposite of dominant) or little lettered allele. therefore, this individual will only be able to pass on a recessive allele which is, in this case, 'a'.

Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.
Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.
*mark as Brainliest ty*
Answer:
It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.

Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine. Some persons get peripheral DXAs, which assess the thumb and heel bone densities.

______________________________
Rabbits can be best described as primary consumers. The correct option is b.
What are primary consumers?The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.
Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.
The animals that eat the primary consumers are known as secondary consumers.
Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).
Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
Thus, the correct option is b.

What do prokaryotes have in common with eukaryotes?
A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.
Answer:
They both have a liquid cytoplasm.
Explanation:
A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).
The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.
Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.
Prokaryotes and eukaryotes both have a nuclear membrane. Option C
What is the commonality?
Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.
The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which of these correctly identifies the two cells described in the table? Your answer: Cell 1 is eukaryotic, and Cell 2 is prokaryotic. Both Cell 1 and Cell 2 are prokaryotic. Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
Answer:
Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
Explanation:
All living cells have been classified into two major domains; Eukarya and Prokarya. This classification was done based on the possession or not of an enclosed structure that houses the genetic material of the organisms called NUCLEUS. Eukaryotic cells possess a membrane-bound nucleus that houses their DNA while prokaryotic cells do not have a membrane-bound nucleus, hence their DNA is found naked in a region of the cytoplasm called NUCLEOID.
In addition to this primary basis (nucleus possession), eukaryotic cells have a linear DNA and other membrane-bound organnelles like mitochondria, Chloroplast, Endoplasmic Reticulum etc while prokaryotic cells have a circular single DNA and have no membrane-bound organnelles.
Based on this comparison, cell 1 is a prokaryotic cell while cell 2 is an eukaryotic cell.

Which of the following areas is located in the frontal lobe of the brain?
Broca's area
O hippocampus
thalamus
Wernicke's area
Answer:
Brocas area
Explanation:
Broca's area is located in the frontal lobe of the brain.
The brain region known as Broca's area is located in the left frontal lobe and is considered the nucleus that controls expressive language.
Thus, in both writing and speech, this portion of the central nervous system specializes in the production of a message with internal coherence and articulated through the language fractions.
In this area, specifically, there are capacities such as:
• Order the phonemes when making a word.
• The organization of words within a sentence.
• The semantic integration of the content to be expressed.
• Motor planning necessary for the expression of language.
Therefore, we can conclude that Broca's area located in the third gyrus in the frontal lobe is responsible for the articulation of language in any of its forms.

The degrees for the wet one was 40 degrees and the dry one was 35. I had to do it three times and the dry one was still 35 on three trys and the wet one was still 40. now calculate the average. (f degrees - 32) x 5/9= the celsius
Answer:
Explanation:
35 + 35 + 35 + 40 + 40 + 40
(the numbers are there three times due to each trial value. you have to account for each.)
From the math you get 225.
Divide 225 by six due to their being six values
37.5 would be the average without the (f degrees-32) x 5/9
(now following the formula you put ((dont know if you have to follow though)))
37.5 - 32 x 5/9 = 3.055555556 degrees celcius.

Organisms may contain up to five levels of organization within their bodies. Which level of organization is best represented by
the liver?
Answer:
ORGAN
Explanation:
The liver is a very important organ in the system of multicellular organisms e.g humans. It performs various functions in the body e.g. detoxification, metabolism etc. As rightly said in this question, multicellular organisms are made up of five levels of organization.
Firstly, all living organisms are made up of CELLS, which are the basic unit of life. Cells come together to form the TISSUE. Tissues that perform similar functions come together to form the ORGAN, the organ that specifically play a similar role in the body are collectively called ORGAN SYSTEM. The various organ systems make up the whole ORGANISM.
In this five level of organization, the liver falls under the ORGAN category because it is made up of cells called Hepatocytes, which come together to form tissues. The tissues collectively make up the LIVER.
