Biology A human body contains about 2.7 cross times 10 to the power of 4 space m i c r o l i t e r s space left parenthesis mu L right parenthesis of blood for each pound of body weight. Each microliter of blood contains about 7 cross times 10 to the power of 4 white blood cells. About how many white blood cells are in the body of a 140-lb person?
The number of white blood cells present in the body of a 140-lb person is 2.646 x 10¹¹.
What are white blood cells?White blood cells are also present in the body. They work for the immune system of the body.
First, calculate the microliters of blood there are in a 140lb person.
140 x (2.7 x 10⁴)
140 x (2.7 x 10 x 10 x 10 x 10)
140 x 27,000
3,780,000 of microliters of blood in a 140lb person
Then, the white blood cells in a 140lb person
3,780,000 x (7 x 10⁴)
3,780,000 x (7 x 10x 10 x 10 x 10)
3,780,000 x (70,000)
264,600,000,000 white blood cells in a 140lb person
Thus, the number of white blood cells will be 2.646 x 10¹¹.

Move the terms into the correct empty boxes to complete the concept map describing the four types of macromolecules
The four main categories of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Each is a vital part of the cell and carries out a variety of tasks. These molecules make up most of a cell's mass when they are all combined.
They play a crucial role in the cell and carry out key tasks. Proteins are necessary for immunity, growth, and maintenance, and they also serve as enzymes, hormones, and other things. The primary source of energy is carbohydrates.Macromolecules, for instance, offer structural support, serve as a reservoir for stored energy, have the capacity to store and retrieve genetic information, and can speed up biological operations.Proteins, carbohydrates, nucleic acids, and lipids are the four main categories of macromolecules that perform these crucial roles in a cell's life.Stores and transmits information are nucleic acids. Carbohydrates: The primary source of energy, a source of fuel, and the building blocks of body structure. Lipid: A lipid is an insulator and a fuel reserve.

Which of the following statements best describes why most animal fats are formed from saturated fatty acids?
The hydrocarbon chains of saturated fatty acids are straight so they can be tightly packed to store more energy in less space.
The hydrocarbon chains of saturated fat cannot pack together closely, which keeps the animal from becoming too large.
The hydrocarbon chains of saturated fatty acids allow fewer hydrogen atoms to bond, which makes the molecule stable for energy storage.
The hydrocarbon chains of saturated fatty acids have bends so they can be loosely packed to store more energy in less space.
Answer:
The hydrocarbon chains of saturated fatty acids are straight so they can be tightly packed to store more energy in less space.

Termites are insects that live in colonies. In a colony, the king and a queen are responsible for reproduction. Workers spend most of their time caring for the other termites and building the nest. Soldiers protect the nest from attacks.
The organization of the termite colony is an example of which benefit of social behavior?
The organization of the termite colony is an example of the benefit of the social behavior which is referred to as division of labor.
What is Division of labor?This involves the separation of work into different units in which each unit is done by separate people. In this scenario, everyone has a task and is done so as to achieve success or a common objective.
In the termite colony, every group have their functions such as the workers spending most of their time caring for the other termites and building the nest and the soldiers protecting the nest from attacks.
This helps to ensure that there is adequate running of the colony with minimal issues which is why division of labor was chosen as the correct choice.

Question 1 of 10 The diagram shows a plant cell. 1 2 3 4 Which label points to the location in the cell where the first step of cellular respiration occurs?
The location in the cell where the first step of cellular respiration occurs is 2, i.e., a mitochondria. The correct option is B.
What is mitochondria?The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular).
Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).
Because they assist in cellular respiration, the process by which energy is extracted from food, mitochondria are known as the powerhouse of the cell or energy manufacturers.
The first stage of cellular respiration, known as glycolysis, takes place in the cytoplasm of the mitochondria.
To produce cellular energy, the six-carbon sugar molecule of glucose is broken down into three-carbon molecules during the process known as glycolysis.
Thus, the correct option is B.

Explain how proteins are involved in mitosis. WILL GIVE BRAINLY
Explanation:
Mitosis and endocytosis are two fundamental cellular processes essential for maintaining a eukaryotic life. Mitosis partitions duplicated chromatin enveloped in the nuclear membrane into two new cells, whereas endocytosis takes in extracellular substances through membrane invagination. These two processes are spatiotemporally separated and seemingly unrelated. However, recent studies have uncovered that endocytic proteins have moonlighting functions in mitosis, and mitotic complexes manifest additional roles in endocytosis. In this review, we summarize important proteins or protein complexes that participate in both processes, compare their mechanism of action, and discuss the rationale behind this multifunctionality. We also speculate on the possible origin of the functional reciprocity from an evolutionary perspective.
Which correctly distinguishes between how a pine tree and an apple tree reproduce?
Answer:
Pine seeds develop in the bracts of the female pine cone and are not surrounded by fruit. The apple seed grows in the ovary of the apple flower and is surrounded by a fleshy wall that grows into the fruit.
Explanation:
How does the pine tree reproduce?
Male pine cones produce pollen, which is like a powder. The male cones release their pollen, which is carried around the air by blowing wind, and hopefully to another female pine cone on a different pine tree. If the pollen reaches a female pine cone, this process is called pollination
How does an apple tree reproduce?
Flowering plants --including the apple tree--reproduce by transferring pollen from the male organ or stamen of one blossom to the female organ or pistil of another. Some flowering plants require no pollinating partner--the flowers are sel- fertilizing.

Some of the reasons of for the sudden development of cell theory after a long break are:
Advancement in technology and technological innovations.More manifestation of greater scientists More co-operation of scientists.As at the time Robert Hooke and Anton Van Leeuwenhoek made their discoveries about cell, both of them and other scientists of that time do not have access to great sophisticated instrument which could aid their research. Their inability to have access to technological innovations do not make them go far.
It is not surprising that Theodor Schwann, Mathias Schleiden and Rudolf Von Virchow made their breakthrough within a short period of time simply because of the use of improvement of technological innovations with which they use to invent the cell theory.
