Answer;
A. myofibrillar proteins in muscle.
Explanation;
Myofibrils are composed of long proteins including actin, myosin, and titin, and other proteins that hold them together.
These proteins are organized into thick and thin filaments called myofilaments, which repeat along the length of the myofibril in sections called sarcomeres.
Myofibrils are bundles of very fine fibers that almost fill the sarcoplasm of a muscle cell, while, Myofilaments (or filaments) are ultramicroscopic, thread-like structures found in myofibrils. In other words, the myofilaments are bundled together to make a myofibril.
B) homologous
C) remedial
D) vestigial
Answer:
The correct answer would be B) homologous.
Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.
For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy. They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).
These organs are adapted to perform different functions in an environment.
It is also observed that these organs developed in the same manner in the embryo and from similar origins.
a. True
b. False
Population density is calculated by dividing the total population of a specific area by the total land area of that area.
The formula for population density is:
Population density = Total population / Total land area
To calculate population density, you need to know the total population and the total land area of the area you are studying. For example, let's say we want to calculate the population density of a city with a population of 500,000 people and a land area of 100 square kilometers.
Using the formula, we can calculate the population density as follows:
Population density = 500,000 / 100 = 5,000 people per square kilometer
This means that in the city we are studying, there are approximately 5,000 people living in each square kilometer of land.
Population density is an important measure that helps us understand how crowded or sparse a particular area is in terms of population. It is often used to compare different regions or to analyze population trends over time. By calculating population density, we can gain insights into the distribution of people and understand the impact of population growth on a specific area.

Answer:
It's A
Explanation: took the test
A) A biome
B) A community
C) An ecosystem
D) A niche
When populations share the environment and interact with the other populations of different living species present in the same are, it is called an ecological community. Thus, the correct option is B.
An ecological community is defined as the group of species which are commonly found together in an area. Ecological communities may include animal or plant assemblages with the similar habitat requirements and contain species which may interact with each other or rely on the similar processes in their particular environment.
An example of ecological community is a forest community which comprises of all the trees, the plant community, birds, deer, squirrels, foxes, fungi, insects, and other local or seasonal species.
Therefore, the correct option is B.

Explanation:
its an ecosystem; reaction between living things and their environment
B. A woman walks in a straight line with the sun to her right at nine o'clock in the morning. Toward which pole does she walk?
C. A man walks in a straight line with the sun to his right at three o'clock in the afternoon. Toward which pole does he walk?
D. A line of longitude
Woman walks in a straight line towards the north pole. In the morning the sun is in the east.
At night the sun is in the west therefore the man is walking to the south pole.
Equator is the termed as the line of latitude.
A line of longitude is known as the vertical lines which are parallel to the prime meridian.
