Answer:
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

How do convection currents work?
Answer:
Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.
Explanation:
Convention currents work by forming a heated fluid expanding making it less dense. As the current rises, it pulls cooler fluid down to replace it.
photosynthesis is an example of...
an exothermic reaction
an endothermic reaction
a reaction that gives off heat
a reaction that emits energy
Answer:
Endothermic reaction
Explanation:
Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.

Hurricanes tend to disperse after making landfall because the land is much hotter than the ocean water.
Answer: False
Explanation:
For a Hurricane to keep going it needs to have hot air constantly going up and cold air coming down. When it gets to land, it loses access to the heat and moisture of the sea which is greater than on land. This forces it to weaken and to eventually dissipate.
Therefore, hurricanes disperse after making landfall because land is not as hot as the ocean water.
What can the reader conclude about homeostasis
Answer: Homeostasis helps animals maintain stable internal and external environments with the best conditions for it to operate. It is a dynamic process that requires constant monitoring of all systems in the body to detect changes, and mechanisms that react to those changes and restore stability.

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilities that the offspring can fold the tongue?
Explanation:
The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case: 1. dominant parent and recessive parent 2. heterozygous parents Answer: 1. dominant parent and recessive parent: dominant parents can be represented by LL and recessive parent is represented by II, so the gametes would be L, L and I, I. so, LL LI LI LI so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I|so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I| In this case, one is pure dominant and two heterozygous whereas only one is recessive the phenotype of offspring that cant fol the so, tongue would be: 75% = 3/4
In what type of cell does the cell wall take the place of the cell membrane ?
A. Plant cells
B fungi cells
C. Cell walls never take the place of a cell membrane
Answer:
Cell walls never take the place of a cell membrane
Explanation:
The cell wall has a texture that is tough, flexible, and occasionally hard and is found outside the cell membrane, hence option C is correct.
What is a cell wall?Plant cells' outside layer is called the cell wall. Only plants and some types of bacteria, fungi, and algae have cell walls.
Bacteria, algae, fungi, most plant cells, and certain archaea all have cell walls. A cell wall is a structure that surrounds the plasma membrane or cell membrane in cells that have them.
Cellulose or chitin are the main components of the cell wall, which is a stiff, semi-permeable structure.
Glucans, chitin, and glycoproteins make up the majority of the cell wall, which is a distinctive structure of the fungus.
Therefore, cell walls never take the place of a cell membrane.

If a muscle contracts isometrically for a long period of time, an EMG (which records the electrical activity in the muscle) recording shows that as the amplitude (frequency of action potential) increases, the contractile force slowly decreases. What is the explanation for this?
Answer:
During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.
