Answer: Frequencies of two alleles in a gene pool before and after many random matings
Explanation:
Frequencies of two alleles in a gene pool before and after many random matings
The allele frequency of h1h1 in offspring is 0.36 if individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles.
What is the frequency of the allele?The number of times the allele of interest is detected in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to compute the allele frequency.
In a population, if individuals mate at random sampling if h1 has a frequency of 0.60, the frequency of h1h1 offspring is 0.36, in the population.
The frequency of alleles can be expressed as a decimal, a percentage, or a fraction. Allele frequencies vary from 0 (present in no people) to 1 (present in all individuals); in a population, all allele frequencies for a particular gene add up to 100%.
Therefore 0.36 is the frequency of h1h1 in the population for individuals at random mates for h1 frequency of 0.60 in the population.

What is cell cycle?
Cell cycle is defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one is G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step is G2 phase in which cell ready to divide.
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
Therefore, Robert Hooke was the first person to observe cells. He observed these cells in a piece of cork. Thus, option A is correct.

Explanation:
The different forms matter can take are referred to as states or countries.
Answer:
Three States of Matter
Learning Objective
Describe the three states of matter
Key Points
Matter can exist in one of three main states: solid, liquid, or gas
The states of matterThis diagram shows the nomenclature for the different phase transitions.
Solids
A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.
In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.
A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.
Liquids
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.
A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.
Gases
Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.
A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).
A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.
Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.

Explanation:
Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.
Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.
Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.
In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

how do oxygen and carbon dioxide cross from the alveoli through the capillary walls and into the blood?
Answer:
The concentration gradient of oxygen in your lungs wants to flow toward homeostasis and oxygen is bound on red blood cells by hemoglobin, along with the attraction of oxygen to hemoglobin. The concentration gradient from carbon dioxide from the capillary to the lungs. There is more oxygen in your lungs (alveoli) than there is carbon dioxide and everything want to reach homeostasis, or level amounts on both sides.
