4. Assertion A: Prokaryotes are identified by the membrane bound cell organelles. Reason R: Prokaryotes are considered as the primitive forms of life. *
a) Both A and R are true and R is the correct explanation of A.
b) Both A and R are true but R is not the correct explanation of A.
c) A is true but R is false.
d) A is false but R is true.

Answers

Answer 1

Answer:

d) A is false but R is true.

Explanation:

Prokaryotes are group of organisms that do not possess a membrane bound nucleus or any other membrane bound organelle in their cell e.g. mitochondria, endoplasmic reticulum etc. They lack such organelles.

However, they are truly considered as a primitive life form; much more primitive than eukaryotic organisms. Examples of prokaryotes are bacteria, archeae etc. Based on the above explanation, it is clear that the assertion (A) in this question is FALSE but the reason (R) is TRUE.

When hypothesizing a possible phylogeny in order to classify taxa,scientists incorporate systematics to
A)provide primarily morphological information.
B)provide molecular or genetic information,as well as morphological information.
C)name organisms using a genus and specific epithet.
D)create a hierarchy of classification based upon reproductive mating patterns.

Answers

Answer:

B)provide molecular or genetic information, as well as morphological information.

Explanation:

Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.

The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.

Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.  

Human body cells are constantly moving water into and out of themselves. Under what conditions can a human body cell achieve homeostasis?

Answers


Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them.

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.

What is homeostasis?

Human body cells are constantly moving water into and out of themselves, and they rely on a complex system of transport proteins and channels to regulate the movement of water and other molecules. Under normal conditions, human body cells can achieve homeostasis by maintaining a balance between the concentration of solutes inside and outside the cell. This balance is maintained through a process known as osmoregulation, which involves the movement of water and solutes across the cell membrane.

Hence, homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. Which section of the diagram represents the phase during
which the cell divides, and what is this phase called?
A. Yellow area: Interphase
B. Yellow area: M phase
C. Blue area: M phase
0 D. Blue area: Interphase

Answers

Answer:

The yellow ares is m-phase

Explanation:

This is where the cell divides into two nucleus.

The blue area in the diagram represents the phase during which the cell divides, and this phase is called the M phase or mitotic phase. Therefore, option C is the correct.

What is mitotic phase?

The mitotic phase, also known as the M phase, is the phase of the cell cycle during which a single cell divides into two identical daughter cells. This process of cell division is essential for growth, development, and repair of tissues in multicellular organisms.

The M phase consists of four stages: prophase, metaphase, anaphase, and telophase. During these stages, the replicated chromosomes condense and align at the metaphase plate, separate and move towards opposite poles of the cell during anaphase, and then decondense and form two separate nuclei during telophase.

The M phase is tightly regulated by a complex network of checkpoint pathways that ensure the accurate segregation of chromosomes and prevent the formation of abnormal cells, which can lead to diseases such as cancer.

Comparing the four most common types of power plants in Alberta (coal, natural

generation? and why?

Answers

Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

Which substance in chloroplasts is a green pigment that absorbs energy for

Explanation:

Chlorophyll is the green pigment that absorbs the light energy for photosystems.

The substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C, as chlorophyll is the primary pigment responsible for the green color of most plants as it reflects green light,

What is chlorophyll?

Chlorophyll is a type of pigment that is responsible for the green color of leaves, stems, and other plant parts, and it is found in the chloroplasts of plant cells, specifically in the thylakoid membranes, where it plays a central role in photosynthesis, and chlorophyll absorbs light energy from the sun. During photosynthesis, chlorophyll absorbs light energy and transfers it to other molecules in the photosystems, where it is used to generate ATP and NADPH, and these energy-rich molecules are then used in the light-independent reactions of photosynthesis to produce glucose and other organic compounds.

Hence, the substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C.

Answer:

The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.

Explanation:

Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.

Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.
