Giraffes get their long necks from stretching for food- an idea discovered by Lamarck
True
False
Answer:
False kind sir/mam
Explanation:
Answer:
The answer is false
Explanation:
The French zoologist Jean-Baptiste Lamarck is usually credited as the first person to suggest that long necks have evolved in giraffes because they allow them to get to the parts other herbivores cannot reach.

Blood is a critical body fluid. What role does blood play in the body? How is it usually cleaned, and how is it cleaned during dialysis?
Answer: Dialysis cleans your blood by passing it through a filter. If you do peritoneal dialysis (PD), the filter is the lining of your abdomen (your peritoneum). If you do hemodialysis, the filter is made of plastic. Your blood is on one side of the filter.
Explanation:Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

According to the USDA, a "consists of a community of individuals who pledge support to a farm operation so that the farmland becomes,
either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.
with reference to evolution of long neck in giraffe explain how natural selection brings about adaptation of species to its environment
Answer:
Explanation:
In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.

A group of lions is chasing a zebra. The lions are most likely responding to which kind of stimulus?
the external stimulus of fear
the internal stimulus of fear
the external stimulus of hunger
the internal stimulus of hunger
Answer:
internal stimulus of hunger
Explanation:
Lions do not fear externally or internally of the zebra because they eat the zebra once they kill it and they are chasing after it so no fear what so ever.
Lions are naturally lazy and hunger is normally why they would be hunting because they need food to survive, however this is not always the case.
there have been a pair of documented pair of male lions known as the Tsavo Man-Eaters, who hunted for sport. Their den contained animal and man bones.
they actually made a movie about it, If you want to watch the movie just look up Ghost in the Darkness. You can actually see the lions in the Field Museum of Natural History in Chicago, Illinois.
Hope this helped you!

MASTERY CONNECT MITOSIS
Answer:
According to the cell cycle data provided in the table, these data indicate that cells spend most of their time preparing for the cell cycle (third option).
Explanation:
The cell cycle is divided into two major phases, interphase —without cell division— and cell division or mitosis. Interphase in turn is divided into three phases prior to the division process:
G1 phaseS phaseG2 phaseAssuming that the complete cell cycle lasts 24 hours, the cell will remain in interphase for 23 hours - preparing for the next division - investing only 1 hour in cell division or mitosis.
The data provided by the table indicate that, at a given time, there will be a greater number of cells in the interphase stages, indicating that cells spend most of their time preparing for the cell cycle.
Glycolysis is an aerobic process. *
True
False
Answer:
False
Explanation:
Glycolysis is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.

explain in your own words : Are mutations good or bad for a population
Answer:
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.Lexie lives at sea level, but her family rented a vacation cabin high in the Rocky Mountains for two weeks. She noticed a difference in her breathing.
An image of a mountain with three circles going up the side of it. The lowest circle is filled with many, smaller circles. The middle circle has fewer circles that are farther apart. The highest circle has the fewest circles that are the farthest apart.
What do the molecules in the circles model regarding altitude?
A. Air pressure increases at higher altitudes.
B. Air density decreases at higher altitudes.
C. There is a greater gravitational pull on air molecules at higher altitudes.
D. Temperature has a decreasing effect on air molecules at higher altitudes.
Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
Fossils of the same type and same age have been found on different continents. If we were to put South America and Africa together, these fossils would even be in the same area! What does this tell us? How could this happen?
Can some one help me plz
Answer:
there have been several cases where fossils of the same type and age where found on different continents.
For example:-
"The Mesosaurus" which is an extinct genus of reptile from the Early Permian and was found in the continents of southern Africa and South America.
This seems to point to the fact that once all the continents were togethe, and they are now separate due to the Continental drift. ( the theory that states that all the continents were earlier one big form of landmass, but they have moved away from each other thus appearing to have "drifted" across the ocean bed."
But again these are all just theories and speculations but findings like these strengthen them and make people believe in these theories. They haven't exactly been confirmed. Like the evolution theory.

You are studying the genomes of deep sea organisms when you come across a brand new species of lantern fish. In the lab, you measure the percent of nucleotides in the nucleus that contain adenine as their base and that percent is 30%. 10. Calculate the percent of thymine nucleotides: _______________ 11. Calculate the percent of guanine nucleotides: _______________ 12. Calculate the percent of cytosine nucleotides: _______________
Answer:
Thymine = 30%
Guanine = 20%
Cytosine = 20%
Explanation:
DNA is a double-stranded molecule made up of long chains of nucleotides (A, T, G, C). Each chain is the strand. However, According to Chargaff, the amount of adenine in a DNA is equal to the amount of thymine while the amount of guanine equals the amount of cytosine. That is:
(A = T) + (G = C) = 100%
All together, they all make up 100%. According to this question, the percent of nucleotides in the nucleus was measured to contain adenine as their base which is 30%.
If Adenine is 30%,. Then Thymine is 30% as well.
A = T = 30+30 = 60%
Hence,
60% + G + C = 100%.
G + C = 100 - 60
G + C = 40%
Since, G = C, 40/2 = 20%. Hence, G = 20% while C = 20%
All together,
A = 30%
T = 30%
G = 20%
C = 20%
