A contraction that generates enough force to move a load is known as ________, whereas one that generates force that equals the load is known as ________.
a. isometric, isotonic
b. isotonic, isometric
c. isometric, eccentric
d. isotropic, isometric
e. isotonic, eccentric
Answers
A contraction that generates enough force to move a load is known as isotonic, whereas one that generates a force that equals the load is known as isometric. The correct answer is B
In an isotonic contraction, the muscle contracts and shortens, generating enough force to move a load or resistance. This type of contraction is commonly seen during activities such as lifting weights or performing repetitive movements against constant resistance.
The muscle changes its length, and the force it generates is greater than the load, resulting in movement.
On the other hand, an isometric contraction is characterized by the muscle generating force, but the length of the muscle does not change, and no movement occurs. In this type of contraction, the force generated by the muscle is equal to the load or resistance applied to it.
Isometric contractions are commonly observed in activities such as holding a heavy object in a fixed position or maintaining a static posture. The muscle remains contracted, but there is no change in its length or movement. Therefore, the correct answer is B.

5. Before the Industrial Revolution took place in England, the gypsy moth was light gray. The factories produced a lot of pollution, and
the bark on the trees in the moths' habitat became dark gray. The gypsy moth could no longer camouflage itself. Use your knowledge
of natural selection to explain how you think the gypsy moth evolved.
Answers
Answer:
here
Explanation:
Through natural selection only the dark grey moths evolved. The trees became covered in dark soot from the factories causing the lighter moths to stand out and be seen easier by predators. The dark grey moths were able to camouflaged better with the soot causing them to be less noticeable to predators and have higher population numbers.

The physical and biological changes of puberty result from changes that occur in the
Answers
The physical and biological changes of puberty result from changes that occur in the endocrine system and reproductive system.
What happens in the endocrine system in puberty ?The endocrine system is responsible for the release of hormones, which regulate growth and development, metabolism, and other physiological processes. During puberty, the hypothalamus in the brain signals the pituitary gland to release hormones that stimulate the gonads (ovaries in females, testes in males) to produce sex hormones, such as estrogen and testosterone.
These sex hormones are responsible for the physical changes that occur during puberty, including the development of secondary sexual characteristics, such as breast development in females, and the growth of body and facial hair in males.

Answers
The correct answer to your question is d. monocyte. Monocytes are a type of white blood cell (WBC) that are agranulocytes, meaning they do not have granules in their cytoplasm.
They typically have a large and kidney-shaped nucleus, making them the smallest WBC in terms of cell size. Monocytes make up about 4-8% of the total number of WBCs in the body and are important in the immune system's defense against foreign invaders, such as bacteria and viruses. Once they enter the tissues, they can differentiate into macrophages, which play a critical role in engulfing and destroying foreign particles. Monocytes also play a role in regulating inflammation in the body.

The name refers to one of the typical characteristics of the group, namely that the seed has two embryonic leaves or cotyledons.
Explanation: Dicots typically also have flower parts (sepals, petals, stamens, and pistils) based on a plan of four or five, or multiples thereof, although there are exceptions. The leaves are net-veined in most, which means the vessels that conduct water and food show a mesh like pattern. In the stems the vessels are usually arranged in a continuous ring near the stem surfarce
Near the surface of the stem, the vessels are often organized in a continuous ring.
What leaf prepare most of the food in dicotyledonous plant?Dicot seeds lack an endosperm for storing nourishment. Because of the lateral meristem, these plants experience secondary growth in their stem and roots.
A region of chlorenchyma cells on the outside and a zone of parenchyma cells on the inside makeup the portion of the cortex that is between the epidermis and the endodermis.
Their architecture and cells are tailored to absorb light and permit gas exchange with the surrounding atmosphere. Additionally, they have vascular systems that transfer water from the roots to the photosynthetic cells.
Therefore, Most leaves have net-veined veins, which means the food and water-conducting vessels have a mesh-like pattern.

Tree-dwelling primates have prehensile tails for gripping branches. Tree-dwelling opossums also have prehensile tails.

Hawaiian honeycreepers, with their elongated, nectar-sipping bills, all evolved from a finch-like ancestor.Answer and Explanation:
Tree-dwelling primates have prehensile tails for gripping branches. Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups. But we can also think about it as a common descent if we consider the farthest primates ancestor. Although still controversial, Plesidiapsi might be considered a common ancestor of primates, that evolved from a ree-dwelling mammal with a long tail. It is believed that this animal used to live in trees. Tree-dwelling opossums also have prehensile tails. Convergence. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Convergence. These are two groups that are very separated from each other, and they developed different traits according to their needs separately. Some of the species of these two groups adapted to feed on the same plant so they needed to develop the same characteristic to obtain nectar.Primates use opposable thumbs to help climb.

Answer:
To summarize what we know to this point, the cellular process of transcription generates messenger RNA (mRNA), a mobile molecular copy of one or more genes with an alphabet of A, C, G, and uracil (U). Translation of the mRNA template converts nucleotide-based genetic information into a protein product. Protein sequences consist of 20 commonly occurring amino acids; therefore, it can be said that the protein alphabet consists of 20 letters. Each amino acid is defined by a three-nucleotide sequence called the triplet codon
