Because the red blood cell is known to have a specific structure, it exhibits a round appearance. Its structure will only change when the body suffers from a lack that alters its form or structure.
What is red blood cell?It is a particular type of blood cell that is produced in the bone marrow and is present in the blood.
Hemoglobin, a protein found in red blood cells, transports oxygen from the lungs to every cell in the body. A complete blood cell (CBC) test often includes checking the blood's red blood cell count.
The shape of red blood cells is a flat disc or doughnut, which is spherical with an indentation in the middle but is not hollow. Red blood cells are minuscule.
The red blood cell has a spherical look because it is known to have a certain structure. Only when the body experiences a lack that changes its form or structure will its structure change.
Thus, the structure is red blood cell.

During the third trimester of pregnancy, the fetus grows in size and weight. So option B is correct.
What features of the baby develop during the third trimester?During the first trimester, the zygote develops into a moving fetus which has working organs such as eyes and ears. In the second trimester, the features of the baby are developed and the movement of the baby can be felt. In the third trimester, the fetus grows in size and weight.
The third trimester starts from the 27th week and continues until the end of the pregnancy. The lungs of the baby are still developing. At the end of the third trimester, the length of the fetus is 19-21 inches and the weight is about 6-9 pounds. In the end, the baby will gain more weight and is prepared for delivery.

hi i need your help guys! Using the periodic table, fill in the following table with the number of electrons in each energy level of the element given.
n = 1 level n = 2 level n = 3 level n = 4 level
Element (maximum 2) (maximum 8) (maximum 18) -----------
Carbon- ________ ________ ________ _______
i think its
carbon- 2 (there are two in the n=1 level) 4 (there are four in the n=2 level)
i might be wrong, but hope this helps :)
Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;
n= 1 ------ 2 electrons
n = 2 ----- 4 electrons
n =3 ----- 0 electrons
n = 4 ----- 0 electrons
Carbon has the electronic configuration; 1s2 2s2 2p2.
This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
This makes a total of six electrons in carbon as shown.

The central nervous system (CNS) is composed of the spinal cord and brain. ALL BUT ONE of the choices below describe
function of the spinal cord.
A)
serves as a minor reflex center
B)
conducts motor information from the brain to various
effectors
C)
processes sensory inputs and initiates appropriate motor outputs
D)
conducts sensory information from the peripheral nervous system to the
brain
Answer:
c)
Explanation:
The central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

The hardness of a steel nail is about 5.5 a certain mineral scratches a steel nail but does not scratch quartz. What could the hardness of mineral be
Answer:
Pick any answer between 5.5 and 7. If you have 6 choose it.
Explanation:
Quartz has a hardness of 7.
The steel ball is 5.5
The mineral must be between these two values. Written mathematically
5.5 < x < 7
So pick any value that is between 5.5 and 7. The other choices would be valuable.

Describe the roles of DNA and genes in inheritance and genetic variation.
Answer:
First, there is only one type of DNA! ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made. There is a complication that some amino acids have more than one code which specifies it - there are plenty of examples where a change of codes (eg a mutation) can result in NO CHANGE in the amino acid which is specified. Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.

Use the drop-down menus to complete the statements. In the first step of meiosis I, DNA condenses to form chromosomes . In the second step, ✔ Each pair of chromosomes lines up in the center of the cell . In the third step, . In the final step of meiosis I, .
Answer:
Prophase I, metaphase I, anaphase I and telophase I.
Explanation:
Prophase I is the phase of meiosis I in which DNA condenses to form chromosomes whereas in metaphase I, each pair of chromosomes lines up in the center of the cell. In anaphase I, each pair of chromosomes is separated from one another which is pulled by the spindle to opposite poles of the cell. In telophase I, the duplicated genetic material is separated that leads to two identical daughter cells.

In your own words , describe how genetic drift , bottlenecks , and the founders' effect csn result in speciation:
Answer:
- Genetic drift: speciation by the accumulation of mutations
- Bottlenecks: the emergence of subpopulations genetically distinct to the original species may contribute to speciation
- Founders' effects: new environments contribute to the emergence of genetic changes and therefore drive evolutionary processes such as speciation
Explanation:
Genetic drift is an evolutionary mechanism in which the allele frequencies in the population change by chance over time. This mechanism can facilitate the emergence of new species due to the accumulation of mutations and population subdivision. Moreover, a bottleneck is a genetic phenomenon associated with a drastic reduction in the size of a population. A genetic bottleneck may lead to the loss of genetic variation and consequently also speciation through population subdivision. Finally, a founder-effect can be defined as an event associated with the colonization of a new environment, which may lead to rapid genetic changes and thus favor evolution (speciation).

The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-
The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.
What are adaptations?Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.
The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.
Therefore, option A. sunlight is used for germinating the fig seeds.
