Answer:
People with lactose intolerance may have a variety of symptoms. It all depends on how much dairy or how many milk-containing foods the person eats and how little lactase the body produces.
Usually within 30 minutes to 2 hours after eating, someone with lactose intolerance will experience nausea, stomach cramps, bloating, gas, and diarrhea. This can be unpleasant, not to mention embarrassing if you're at school or out with friends.
Because many people may think they're lactose intolerant when they really aren't, it helps to see a doctor who can diagnose the condition correctly and advise you on ways to manage it.

How does gas exchange occur in plants?
Plants obtain the gases they need through their leaves. They require oxygen for respiration and carbon dioxide for photosynthesis.
Explanation:
The gases diffuse between the cells spaces of the leaf through pores, which are normally on the underside of the leaf - stomata. From these spaces they will diffuse into the cells that require them.

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
Explanation:
I chose this because it seems like the most logical explanation.
"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.
What is biodiversity?Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.
The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.
In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is, ecosystem X has a greater amount of biodiversity. So, during the drought, the bison in ecosystem X are better able to survive.
Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

The hypothesis would not have been supported
by the data if...
A. traits independently assorted in
approximately a 9:3:3:1 ratio.
B. the traits for white fur and red eyes were
always inherited together.
C. all the F1 offspring had the same phenotype.
Answer: B
the traits for white fur and red eyes were always inherited together.
Explanation:
The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.
What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Yuki has a bowl of ice. She places the ice in a warm room and watches as it melts into liquid water. Yuki then places the liquid water over a Bunsen burner and heats it until it vaporizes. Explain what happens to the water molecules in Yuki's experiment; from the beginning to the end of the experiment.
Answer:
ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.
Explanation:
Answer:
a) For example, a cat may see a saucer of milk. Information from
the cat’s eyes travels along nerve cells to the brain, where the brain
processes the information. If the brain decides it wants the milk,
the brain sends a signal to the muscles in the cat’s limbs, and the cat
moves to the saucer of milk and drinks it
Explanation:
b) For example,
specialized cells in the leaves of trees detect the decrease in sunlight
as winter approaches. Chloroplasts then reduce production of green
chlorophyll. As existing chlorophyll is broken down, other coloured
particles are revealed, creating the beautiful red- and orange-coloured
leaves we see during autumn. Th e leaves eventually die and fall off . In
the spring, increased sunlight and warmer temperatures promote the
production of new leaves containing large amounts of chlorophyll, and
the green colour returns to the leaves.

The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth
Answer:
C) exponential growth
In the given figure, exponential growth curve is pictured.
What is exponential growth?It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:
Lag phaseExponential phaseStationary phaseDeath phaseIn the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.
In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.
Thus, the pattern of growth demonstrated in the given figure is exponential growth.

Why do surface currents move in circular patterns?
Answer:
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
Surface currents are created by three things:
global wind patterns
the rotation of the Earth
the shape of the ocean basins
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Answer:
The Coriolis effect causes winds and currents to form circular patterns.

Which would be true of sexual reproduction?
a
increases survival rate
b
involves one parent
c
increases genetic diversity
d
produces identical offspring
Answer:
c increases genetic diversity
Explanation:
Answer:
C. increases genetic diversity
Explanation:
First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

What two diseases have been studied together that provide evidence of evolution in
humans?
A)malaria and ebola
B)sickle cell anemia and malaria
C)cytochrome c disease and plasmodium fever
D)iron-deficient anemia and yellow fever
Answer:
sickle cell anemia and malaria
Explanation:
Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.
The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.
What is sickle cell mutation?
The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.
The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.
