Human Population Growth and Overpopulation
Can someone please help me I don't understand what I have to do.
Answer:
all you're trying to do is create a histogram of what has happened in the past and what could happen in the future.
Explanation:
for example and AD you feel the first little bar because it's not more than a billion and its last therefore it would be the zero billion
and then for 1850 you feel to bars because they had 1 billion people so therefore you feel the 0 billion and the 1 billion part
What adaptation do seeds dispersed through ballistochory have?
a)
sail-like structure
b)
smooth and aerodynamic
c)
hollow on the inside
d)
pleasant smell and taste
Answer:
smooth and aerodynamic
Explanation:
Seeds are usually smooth, like a baseball, so that they cut smoothly through the air and don't have a lot of wind resistance.
The adaptation that seeds dispersed through ballistochory has smooth and aerodynamic. The correct option is b.
What are adaptations?Adaptation is a biological process that is done by many plants and animals to survive in given conditions. Adaptation is causing the partial or full change in their body or functions to match with the environmental conditions.
Plants with ballistochory means possibly ejects by the seeds full stop this adaptation or evolution happened in which seats are dispersed into many tentacles and seats are dispersed into soils for pollination this comes under wind dispersion.
Seeds launch an angle and release the elastic energy store in the fruit. These adaptations are smooth.
Therefore, the correct option is b. smooth and aerodynamic

Which of the following describes a scenario that could increase the winds of the jet stream?
O Faster global convection currents
O Decreasing radiation from the sun
O Equal heating of the Earth's surface
O Stopping conduction from the ground
Answer:
faster global convection currents!
Fortunately I just took this quiz and received 100%!
The statement that explains scenerio that can bring an increase to winds of the jet stream is A: Faster global convection currents.
Jet streams can be regarded as a fast flowing as well as narrow and meandering, air currents which is found on Earth and other planet. It is a bands of strong wind which moves to east from west in the globe.The wind of jet stream do increase by the action of wind current, because convection current do aid the movement of this this wind from a place to the otherTherefore, option A is correct.

Determine whether the following statement is true or false. If false, select the choice that will make it true. "Aerobic respiration produces Glucose."
A. True
B. False, it produces proteins.
C. False, it breaks ATP into ADP.
D. False, it produces ATP.
Answer:
D. False, it produces ATP
The statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP. Thus, the correct option is D.
What is Aerobic respiration?Aerobic respiration may be defined as a chemical process in which oxygen is utilized in order to construct energy from carbon dioxide and water. This type of respiration typically takes place in the presence of oxygen to catalyze a given set of reactions.
Aerobic respiration occurs in presence of water. It takes place with help of glucose further convert into pyruvate to derive carbon dioxide, water, and energy in form of ATP. The process of aerobic respiration is also known as oxidative metabolism and cell respiration. In this process, glucose reacts with oxygen to form ATP.
Therefore, the statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP along with carbon dioxide and water. Thus, the correct option is D.

Listeriosis is of particular concern for pregnant women because pregnant women are more likely than other population groups to get listeriosis. listeriosis can cause fetal death. Listeria bacteria can cross the placenta and infect the fetus. All of the choices are correct.
Answer:
The correct answer is ''All of the choices are correct.''
Explanation:
Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.

Which of the following species is Endemic?
A. Geese on the East coast of the US
B. African elephants at the zoo
C. Invading Japanese beetles found eating crops in North American farms
D. Lemurs isolated to the island of Madagascar
Answer:
D. Lemurs isolated to the island of Madagascar
Explanation:
Endemic is to be native and restricted to a certain place.
Endemic species are organisms that are limited and confined to a particular region. Lemurs show endemism as they are isolated to the island of Madagascar. Thus, option D is correct.
What is Endemism?Endemism is a biological term used to depict the distribution of the organism in an area that becomes its habitat. It is shown by species that are limited and bounded to one geographical location.
Endemism is shown by the species due to genetic isolation that separates the population or the species in a geographical area and does not allow the genetic material to exchange by reproduction.
Koalas and Kangaroos in Australia, Lemurs in Madagascar, lion-tail macaque and Nilgiri blue Robin in India, and camellia plant in Japan are some endemic species.
Therefore, option D. the Lemurs in Madagascar are an example of endemic species.

eople that have a single allele (gene copy) for sickle cell anemia are typically not sick from the disease and are said to be carriers of sickle cell trait. These people will more often live in the malaria belt of sub-Saharan Africa. The most likely explanation for this is ________. malaria is a cause of sickle cell trait people with sickle cell trait have a better chance of surviving malaria sickle cell trait is passed on to the biting mosquitoes as malaria There is no correlation between a single allele for the pathology and the ability to survive or fight malaria.
Answer: people with sickle cell trait have a better chance of surviving malaria.
Explanation:
Malaria is a very prevalent disease in the malaria belt of Sub-Saharan Africa which includes much of western and central Africa. The people here have therefore grown to have better immunity to malaria by developing the sickle cell trait.
This has helped them survive both malaria and sickle cell anemia which doesn't affect them even though they carry the sickle cell trait.
