Answer:
A.
Explanation:
Passive transport is defined as the movement of ion and other molecules through cell membrane without any energy input while active transport is the movement of ions and other molecular substances across cell membranes with an energy input which allows, molecules to move from a region of lower concentration to a region of higher concentration.
Uptake of iodide ions by thyroid cell is an active transport which is mediated by sodium/iodide symporter (NIS) protein, found in basolateral membrane of thyroid follicular cells. As the concentration of iodide ions is higher in thyroid cells, active transport make movement of iodide ions form extracellular fluid (lower concentration) to thyroids cells (higher concentration).
Hence, the correct option is A.
Answer:
A.active transport, because the cell must pump ions from regions of low concentration to high concentration

When substance change state, the mass stays the same.
True
False
Answer:
True
Explanation:
If an ice cube melted, The amount of water in the ice cube would not be more or less than the water left over from when the ice cube melted. Mass must always stay the same, it cannot be created or destroyed. If a change in state ever occurred and there is more or less mass, the experiment was either contaminated or not kept in an air tight container. Chemicals can dissipate into the air and other chemicals not originally in the reaction can be unintentionally mixed in, fluctuating the level of mass and volume.

If each dominant allele adds 10 cm to an adult humans hieght which of the following genotypes would produce the tallest adult?
AaBbCc
AaBbcc
AABbCC
Answer:
AABbCC
Explanation:
Has the most dominant genotypes out of all of them. The first one is fully compromised of heterozygous genotypes, and the second one contains a homozygous recessive genotype.
If each dominant allele adds 10 cm to an adult humans height the genotype that would produce the tallest adult is AABbCC.
What is an allele ?The term allele denotes the variant of a given gene. An allele can either be a dominant allele or a recessive allele. The dominant allele masks the effect of the recessive allele.
What is a genotype ?The genotype of an organism is its complete set of genetic material.
Since each dominant allele adds 10 cm to human height, therefore the genotype AABbCC has maximum dominant alleles (5). Hence, it will add 50 cm to the height.

What would happen if the hormone levels did not have their peak just before
day 14?
A. Undeveloped eggs would not start to mature.
O
B. Ovulation would not happen.
O
C. The egg would attach to the uterine wall.
O
D. The woman would become pregnant.
Without the peak of hormones around day 14 of the menstrual cycle, ovulation wouldn't occur as this process is triggered by the rise in specific hormones. As a result, it would prohibit the release of a mature egg for potential fertilization.
Explanation:The context of this question is related to the female menstrual cycle. Hormones play a vital role in regulating this cycle. Around day 14 of a typical 28-day menstrual cycle, levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) peak to stimulate ovulation, which is the release of a mature egg from the ovary. If these hormone levels did not reach their peak, ovulation would not occur. Therefore, option B, 'Ovulation would not happen', appears to be the correct answer. It's essential to note that without ovulation, pregnancy is not possible because there is no egg for sperm to fertilize.

Phototransduction is the process:
Answer:
Phototransduction is the process by which a photon of light is changed to an electrical signal, occurs in the photoreceptors.
Explanation:
HOPE THAT HELPS!!
The process of phototransduction transforms light into a shift in the electrical potential of the cell membrane.
How does Phototransduction work?This procedure entails the successive activation of several signaling proteins, which ultimately results in the opening or closure of ion channels in the membrane of the photoreceptor cell.
A suitable analogy for G-protein-mediated signal transduction is phototransduction.
Which are concentrated in large amounts in the outer segments of photoreceptors, has made it easier to conduct biochemical studies of the route.

Explain how birth rate, immigration, death rate, and emigration affect population growth
Population growth is determined by the interplay of birth rates, death rates, immigration, and emigration. These factors are synthesized into a growth rate equation, indicating how each contributes to the overall population change. Demographic transition further affects these rates and, consequently, population size and growth rate.
The population growth rate is the measure of how fast a population size changes over time, and it's influenced by four main factors: birth rate, death rate, immigration, and emigration. The birth rate adds to the population when it exceeds the death rate, while the death rate reduces the population when it is higher than the birth rate. Immigration adds individuals to a population as they move into an area, while emigration removes individuals when they leave an area. The population's growth rate can be summarized by the equation: r = (b + i) - (d + e), with 'r' representing the growth rate, 'b' the birth rate, 'i' the immigration rate, 'd' the death rate, and 'e' the emigration rate.
If a country progresses through the stages of the demographic transition model, we would typically see the birth and death rates high in the early stages, leading to rapid population growth. As the country develops, the death rate tends to decline first, followed by a decline in the birth rate. As a result, the population growth rate often slows down, and the population size may stabilize or even shrink if deaths exceed births and emigration is higher than immigration.

Humans cut down trees in a location. This caused an increase in temperature and decrease in rainfall in that location. Which of these Earth systems interacted to produce this difference in climate?
biosphere, cryosphere, and geosphere
atmosphere, hydrosphere, and geosphere
biosphere, atmosphere, and hydrosphere
cryosphere, atmosphere, and hydrosphere
Answer:SECOND ONE
Explanation:
hope this helps
The Earth systems that interacted to cause climate changes such as an increase in temperature and a decrease in rainfall due to deforestation are the biosphere, atmosphere, and hydrosphere.
Explanation:The interaction of Earth's systems in this scenario involves the biosphere, atmosphere, and hydrosphere. When humans cut down trees, which are part of the biosphere, there is a decrease in the amount of carbon dioxide that is absorbed, leading to higher levels of this greenhouse gas in the atmosphere. This exacerbates the greenhouse effect, which increases Earth's temperature. Furthermore, trees contribute to the water cycle which affects the hydrosphere by releasing water vapor into the atmosphere during transpiration, helping to regulate rainfall. Without trees, this process is hampered, potentially decreasing rainfall in the region.

SimilarityAlthough rainforests and deserts are very different, they do have something in common. They both have mountains and steep canyons.
What defines a desert?One thing all deserts have in common is that they are arid or dry. Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall.
What is tropical forest?A tropical forest is a type of forest found in areas with high regular rainfall and no more than two months of low rainfall, and consisting of a completely closed canopy of trees that prevents penetration of sunlight to the ground and discourages ground-cover growth.
