Answer:
C
Explanation:
Father/mother must each donate a blood gene to the child. Father must have a genotype of ii because O blood is recessive. Thus, the kid must have one O type gene. However, the kid has A type blood overall, so the kid must have an A (dominant) gene as well. Thus, the answer is IAi.

Moving up the food chain, the energy available to the organisms decreases due to metabolic heat. (You can add the second law of thermodynamics into it, if you want)
For example, in the rules of tens, the plants start with 100% of the energy but the fi red t level consumers gain 90% of the energy due to the fact energy transfers through heat.
Because of the change is available energy, consumers at the higher levels of the food chain are forced to hunt larger amounts of prey to sub stain themselves.

Answer: 1Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive. 2Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. 3In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. 4In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.5: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. ... Water has a concentration gradient in this system. Thus, water will diffuse down its concentration gradient, crossing the membrane to the side where it is less concentrated. 6Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. 7In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.8During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.9Endocytosis definition and purposes. Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle. ... Endocytosis occurs when a portion of the cell membrane folds in on itself, encircling extracellular fluid and various molecules or microorganisms.10Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell, as shown in Figure below. Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin
Explanation:
The type of membrane protein that gives cells specific identity are called:
Markers
Channels
Receptors
Pumps
Aquaporins
Answer:
Membrane markers allow cells to recognize one another, which is vital for cellular signaling processes that influence tissue and organ formation during early development. This marking function also plays a later role in the “self”-versus-“non-self” distinction of the immune response.

Inside the cell is 40% helium and outside the cell is 20% helium. Which of
the following will occur? *
A. helium will move out of the cell
B. helium will move into the cell
C.helium will not move
Answer:
A. Helium will move out of the cell
Inside the cell the concentration is higher than concentration off outer cell so the inner helium well more about of cell
Answer:
[tex]\boxed {\boxed {\sf A. \ Helium \ will \ move \ out \ of \ the \ cell}}[/tex]
Explanation:
Diffusion is the movement of particles from a high concentration to a low concentration. This is the process occurring in this question.
In this cell, 40% helium is inside the cell.
20% is outside of the cell.
40 is greater than 20. Therefore, the helium wants to move from the area of 40% to 20%, which is also from the inside of the cell to the outside. Basically, the helium moves out of the cell.
So, the best answer is choice A: helium will move out of the cell.

The seed plants became dominant during the late ___ when the climate became ___.
The seed plants became dominant during the late Paleozoic era when the climate became drier and more arid.
The dominance of seed plants during the late Paleozoic era was driven by a combination of their unique reproductive strategies, water-conserving adaptations, and the changing climate that favored their survival and proliferation.
During the late Paleozoic era, which lasted from approximately 298 million years ago to 252 million years ago, seed plants, including gymnosperms and later angiosperms, became the dominant plant group on Earth.
This era is also known as the "Age of Seed Plants" due to the significant diversification and success of seed-bearing plants.
One of the main factors that contributed to the rise of seed plants during this time was the changing climate. The late Paleozoic era saw a shift towards drier and more arid conditions, with the decline of the swampy and humid environments that characterized earlier periods.
Seed plants have several adaptations that allowed them to successfully colonize and dominate these drier environments. One key adaptation is the ability to produce seeds, which are reproductive structures containing embryos and stored nutrients.

2)The cell is the basic unit of structure and organisation in organisms.
3) Cells arise from pre-existing cells.
2. The first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
3. law of elasticity (Hooke's law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory
4. His discovery of the nucleus and its role helped to put together the cell theory, which states that all living organisms are composed of cells, and cells come from pre-existing cells.
5. He published his findings and called the process he saw “binary fission”. He concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter.
6. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory.
7. that the sperm and egg were composed of cells and that humans are formed of cells from beginning to end.
8. In 1855, he further developed his ideas by publishing his famous aphorism omnis cellula e cellula which became a part of the foundation for cell theory. Virchow's theory stated that just as animals are unable to arise without previously existing animals, cells are unable to arise without previously existing cells.
9. Pasteur's experiment showed that microbes cannot arise from nonliving materials under the conditions that existed on Earth during his lifetime. The experiment had to do with Pasteur adding nutrient broth to flasks, bent the necks of the flasks into S shapes, and then boiled the broth to kill any existing microbes.
