how to read a phylogenetic tree ( add details pls)

Answer:

I think the answer is A

Explanation:

Because all cells must perform basic functions to survive

In an organism with more than one cell, each of its cells must perform all basic life functions to survive. Thus option A is correct.

Cell is the basic unit of any living organism present  in animal, plant, microbes etc; Bacteria are unicellular organism where as higher eukaryotic organisms are multicellular in nature like plants and animal cell.

Prokaryotic cells are the most simplest form of cell which  have a cell membrane, cytoplasm, ribosomes where protein synthesis occur, and nucleoid genetic material are present, most of bacteria have cell wall,   reproduce by binary fission.

The eukaryotic cells have all the organelles like it has outer covering  cell membranes, cytoplasm, ribosomes, and nucleus, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum, Golgi apparatus for protein sorting and exporting.

It has mitochondria the power house, a cytoskeleton for structure of the cell and communication, and  lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

Thus option A is correct.

The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons and dendrites.

please mark brainliest.

The functional cell of the nervous system is neurons.

The nervous system is the main controlling system of the living body. It consists of the brain and the spinal cord. The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system.

Neurons are the cells of the nervous system. The cells are branch-like structures like the roots of a plant, they contain absorb the information using electrical impulses and transport it into different areas of the brain.

The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells. The neuron cells' function in the peripheral system is to collect the signals and information and to send it to the central number system, which contains the brain for processing.

Therefore, neurons are the functional cell of the nervous system.

Light is required for respiration and food production , absorbed through chlorophyll. So it's (C).

Mesophyll is photosynthetic tissue and splitting of water is known as photolysis. (A)

Plant converts light energy into chemical energy, and glucose is the ultimate product. (B)

Light is needed for photosynthesis, but not during dark reactions.(A)

Plants and other living things use a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.

The first stage of photosynthesis, known as the light reaction, uses light energy to produce ATP and NADPH, whereas the second stage, known as the dark reaction, uses the energy from ATP and NADPH to produce glucose.

Explanation:

Although a single motor neuron can innervate several muscle fibers, each muscle fiber is innervated by only one motor neuron

Lipids: oil, cholesterol, beeswax

Carbohydrates: Glucose, Fructose, Starch, Glycogen, Cellulose

Nucleus acids: DNA, RNA

Answer:

The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.

Answer: The answer is B

a single-celled protozoan with a selectively permeable membrane that is placed in a hypertonic glucose solution. so the glucose will enter the cell by diffusion. Option B is the correct answer.

Solvent and solute combine to form a solution. Depending upon the concentration of solute, the solution is of three types: hypertonic solution, hypotonic solution, and isotonic solution. The solute concentration in a hypotonic solution is less than the solvent concentration. The solute concentration in a hypertonic solution is greater than the solvent. In an isotonic solution, both the solute and solvent concentrations are equal.

When the cell is placed in a hypertonic glucose solution, the cell takes glucose into the cell by certain transporters or channels. Glucose is a polar molecule that cannot easily pass through the membrane. Hence, there are many transporters and channels present in the cell membrane. The movement of glucose is called "facilitated diffusion." No energy is required.

Hence, option B is the correct answer, as the glucose is diffused.

Explanation:

The traits bird and its closest relative share are eggs with shell, amniotic eggs and four limbs.

A trait is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure).

Simple (or Mendelian) inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other. The pattern of inheritance of simple traits depends on whether the traits are controlled by genes.

Biological traits describe species' physiology, morphology, life history, and behavior, capturing both inter-specific interactions and the connections between species and their environment.

Active transport in plant

Explanation:

Active transport in plants

For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. Active transport then occurs across the root so that the plant takes in the ions it needs from the soil around it.
