Answer:
When this happens, sometimes the cell commits a special type death is called apoptosis. Apoptosis, otherwise known as programmed cell death, ensures that if mitosis goes wrong and cannot be fixed, the cell does not continue to divide, as this would lead to the production of mutant cells that might cause problems.

Why did the human population grew from 1000 BCE until about 1930?
Human population has grown exponentially over the past century. It has done so largely by producing large amounts of food, and learning how to control disease. Ten thousand years ago, when humans first invented agriculture, there were maybe one million humans on the planet.

Answer: Answer: Answer: Answer:
describe evidence from biogeography that species evolve adaptations to their environment
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

The student plans this cutting into a pot with soil, and he grows along side the original point where it came from. Which explanations best match with the description an image shown here in the scenario? Select all that apply.
Answer:
If its on usa test prep it would be
A) The new root growth is a result of meiosis
B) the new plant formed from as reproduction
D) The new plant is genetically identical to the original plant.
The new plant grows vegetatively from the cutting and will look exactly like the original plant.
Vegetative propagationCutting is a form of vegetative propagation attribute of some organisms.
Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.
Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.
Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

Do turtles have exoskeleton?
Answer:
Mark me brainliest （⌒▽⌒）Explanation:
The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structureNo. Turtles are vertebrate animals with internal skeletons. Even the shell is made of bone covered by a thin layer of tissue and keratin scutes (material similar to your fingernails). The entire skeleton is on the inside. A turtle’s shell is no more an exoskeleton than your own skull is.

The published data for the map distance between the gene and the centromere is 26 map units. You just calculated the map distance as 17 map units. What is the best explanation for this disparity
Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.
A linkage map is based on the frequency of recombination events between genes or molecular markers.
This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.
Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it
The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.
We can arrive at this answer because:
When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.

What is the linear momentum of an object with a mass of 10 kg and velocity of 100 m/s?
Here,
Mass of the object = 10 kg
Linear momentum of the object=100kg m/s
And , we have to find it’s velocity??
But we do know that linear momentum (p) is mass(m)× velocity (v)
P=m×v
V=p/m
Substituting the value here we get,
V= 10/100
Therefore, v= 0.1m/s.
why is cooking faster with a pressure cooker
As the pot is heated, the temperature inside increases until the water starts to boil. ... At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.
In urban areas the food insecure families are those whose working members are generally employed in low paid occupations and casual labour market.

please explain why.
You close your eyes, with your hand in front of your face for one minute. You quickly blink your eyes and find that even with your eyes closed, you can "see" your hand briefly. Why does this occur?
1) because elaborative rehearsal has transferred this image to your Long-Term Store/Memory, where it is stored indefinitely
2) because auditory images are held in Sensory Store/Memory for up to several seconds
3) because visual images are held in Sensory Store/Memory for up to about 1/4 second
4) because maintenance rehearsal keeps this image in your Short-Term Store/Memory indefinitely
Answer:
because visual images are held in sensory store/memory for up to 1/4 second
You can "see" your hand briefly because visual images are held in Sensory
Store/Memory for up to about 1/4 second.
When the sensory organ involving the eyes views an object briefly, the
information is usually passed to the brain which tells the type of object and
the action to take in response to the stimuli.
In this case, the visual image are usually held in the sensory
store/memory(brain) for few seconds which is why it is seen briefly even
after closing the eyes.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP
Answer:
B
Explanation:
The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2
the answer is not exact, but it is the closest to the actual equation
The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.
What is photosynthesis?Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.
The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.
Thus, option B is the correct option.
