Ice is the natural element that is one of the best preservers of prehistoric life.
Plants fossils help scientists to identify different ice ages.
What is Fossil?A fossil may be defined as the dead and organic remains of past organisms that are buried under the earth's surface millions of years ago.
The presence of prehistoric life may be best understood by the natural elements such as ice that has a definite composition with respect to time.
Plants and animal remains illustrate the occurrence of fossils which assist scientists in estimating the different ice ages.

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.
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.

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.

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.

In addition to this existing biodiversity, the region has an extraordinary rate of species discovery, with more than 2,216 new species described between 1997 and 2014 alone.
While Sahara hosts some 70 species of mammals, 90 species of resident birds, 100 species of reptiles, and numerous species of arthropods (invertebrates that have jointed limbs, segmented bodies and external skeletons)
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.

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.
Therefore changing light into an electrical signal is referred to as Phototransduction and is done by photoreceptors.

A species with 12 protons and 10 electrons is the magnesium ion with a plus 2 charge. Option C is correct.
Magnesium (Mg²⁺) is the cation of magnesium, the metal cation of magnesium divalent, and the metal dication of magnesium monoatomic. It has the functions of a cofactor.
It is mainly used in the form of Magnesium hydroxide in the milk of Magnesia, a white, slightly alkaline, water-soluble suspension of magnesium hydroxide, formulated at approximately 8% w/v.
Magnesium has 2 electrons in the outermost orbit, the 3s orbit. It can donate 2 electrons out of 3s orbit and achieve +2 charge. Due to the octet principle, the magnesium atom donates 2 electrons to form a stable octet.

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.
