Primates, including humans, have different modes of locomotion such as bipedalism and brachiation due to specific morphological adaptations. These changes have been hypothesized to have evolved from our arboreal ancestors. Each primate subgroup, from lemurs to humans, has adapted in different ways to their environment.
Different modes of primate locomotion includes a series of movements like bipedalism, quadrupedalism, brachiation (swinging from branch to branch), leaping, and more. These locomotion modes are possible due to several morphological adaptations such as a rotating shoulder joint and thumbs and big toe widely separated from other digits, which allow for gripping branches. For instance, in bipedal locomotion, one leg is on the ground (stance leg) and the other is in the air (step leg) striding forward.
All primate species are believed to have descended from arboreal ancestors hence the adaptations for climbing trees. However, not all primate species today are arboreal. Large brains, stereoscopic vision, and a flattened nail instead of claws are among the specific characteristics of primates, especially those adapted to arboreal life.
Interestingly, humans are part of the primate order, which also includes lemurs, monkeys, and apes. These primate groups possess the necessary physical adaptations for different modes of locomotion, which allow them to live in diverse environments from tropical forests to savannahs.

Starch, cellulose, and glycogen are polysaccharides composed of glucose. Starch and glycogen, both used for energy storage, are branched polymers with α-1,4 and α-1,6 glycosidic linkages while cellulose, used for structural support, forms a linear structure with rigid β-1,4 glycosidic linkages.
Starch, cellulose, and glycogen are all polysaccharides composed of glucose units. Starch is a branched polymer which is the primary form of energy storage in plants. It has α-1,4 and α-1,6 glycosidic linkages without the tight crosslinks of cellulose, hence it is less rigid than cellulose.
Cellulose is a linear chain of glucose molecules and forms rigid β-1,4 glycosidic linkages, serving as a structural component in the cell walls of plants and other organisms. Due to its arrangement, it is rigid and forms the structural fiber in plant-based foods.
Glycogen is also a branched polymer, and is the principal storage form of glucose in animal cells and bacteria. While the glycosidic linkages in starch and cellulose differ, glycogen, similar to starch, has α-1,4 and α-1,6 linkages. These different molecular structures allow carbohydrates to serve varied functions such as energy storage (starch and glycogen) and providing structural support (cellulose).

Answer;
-Cytoplasm
Explanation;
Cytoplasm is a jellylike substance in both the animal and the plant cell containing important chemicals and acts like a matrix for the cell organelles.
-The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts. Cytoplasm has various functions in the cell, such as;
-Important activities of the cell occur in the cytoplasm. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity. It is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place.
it creates consistency in cells
it creates cells that are similar
it creates cells that are copies
Answer:
D) It creates cells that are copied
Explanation:
I just did it on a test.

B. Blood pressure would increase between heartbeats.
C. Blood flow would be temporarily blocked between heartbeats.
D. Blood volume would increase between heartbeats.
Answer:
The correct answer is option A, Blood pressure would drop during a heartbeat
Explanation:
When the arteries get constrict, the walls of arteries reduces the space/volume with in the arteries which causes blockage for a very minute time period. When the flow is blocked the blood pressure increases, while when the walls are released the pressure reduces but the flow increase.
This process is also refered to as Vasoconstriction and it is a normal process which stabilizes the blood pressure.
B. There will be a 1:1 ratio of mutant to wild-type.
C. All of the F1 progeny would be wild-type.
D. All of the F1 progeny would display a novel mutant phenotype that differs from that of the parents.
The answer is not C.
Answer:
All of the F1 progeny would be wild-type.
If the two mutations are in different genes, then we expect complementation to occur (each mutant strain provides a functional copy of the gene that is defective in the other strain) and wild-type progeny to be produced
In genetic complementation testing, a 1:1 ratio of mutant to wild-type phenotypes is expected in the progeny when the two mutations are in the same gene.
In genetic complementation testing, crosses are performed between pure-breeding strains for recessive mutations that confer the same mutant phenotype. If the two mutations are in the same gene, then the expected phenotypic ratio among the progeny is a 1:1 ratio of mutant to wild-type, which means equal numbers of individuals displaying the mutant phenotype and individuals displaying the wild-type phenotype.
