Which definition is the best for “semipermeable membrane
Answer: A semi-permeable membrane is that which only allows certain
substances to pass through.
Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

which is a nonmendelian trait
Answer:
Polygenic traits are considered non-Mendelian because their alleles are located on more than one gene which allows for more alleles and phenotypes.
Explanation:
Examples of polygenic traits are hair color and height. Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
The cells of a pineapple plant have 50 chromosomes in their nuclei. How many chromosomes are there in the male nucleus in a pineapple pollen grain?
Answer:
25 chromosomes
Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
So, in the exposed example
"...cells of a pineapple plant have 50 chromosomes in their nuclei..."
These might be diploid somatic or germ cells. The number of chromosomes, 2n = 50.
Germ cells in plants suffer meiosis and produce gametes.
Gametes of plants are ovocell and pollen grains. Ovocell is the feminine gamete, while the pollen grain is the masculine gamete.
The pollen grain is haploid and its number of chromosomes n = 25.

Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.
how does secondary succession differ from primary succession? it begins on bare rock or land, it begins where no plants have grown, lichens and mosses form soil first, soil nutrients are already in place
in georgia or in the crib
Answer:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Fatty acids are a component of what type of macromolecule?
Answer:
Lipids
Explanation:
read textbook
Fatty acids are a component of lipids macromolecules.
Fatty acids and lipidsFatty acids are a component of lipids. Lipids are a diverse group of macromolecules that include fats, oils, phospholipids, and sterols. Fatty acids are the building blocks of lipids.
They are long hydrocarbon chains with a carboxyl group at one end. Fatty acids can be saturated (no double bonds) or unsaturated (one or more double bonds).
When combined with glycerol, fatty acids form triglycerides, the most common type of lipid used for energy storage in organisms.

Organelles are structures within the cell that perform important functions. Which of the following correctly matches
organelle with its relationship to the whole cell?
mitochondria - provides the instructions for making proteins
B nucleus - provides protection to the outside of the cell
chloroplasts - trap light energy and change it into food for the cell
cell membrane - changes the energy the cell gets from food into a form the cell can use lo
Answer:
Chloroplasts trap light energy and chnage it into food for the cell
Explanation:
In the chloroplasts is where photosynthesis occurs. Photosynthesis is the process by which plants make their own food by using carbon dioxide water and sunlight. The chlorplast traps the energy from the sunlight and then the reaction between the carbon dioxide and water can occur

Answer:
Population of lions are more than cheetahs and zebras.
Explanation:
The chart provides information about the population sizes of Lions, Cheetah and Zebras. According to this information, population of lions is the greatest as compared to Cheetah and Zebras. This is due to suitable conditions for the lions such as food and shelter etc in that jungle of Africa as well as strong competitor and its aggressive behaviour make them successfully survive and increase its population in the jungle.
