Ans:using a filament of spirogyra in a laboratory Demonstrate how plasmolysi wil occur​

Answers

Answer 1

Answer:

plasmolysis is the shrinkage of protoplast from the cell wall under the influence of a hypertonic solution.this can be observed by placing the fresh filament of spirogyra in a 10% solution of common salt.the cell undergoes exomosis.

Answers

Answer:

Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.

All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

What is connective tissue?

Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.

Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.

Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Hence, All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

Answer:

Natrual selection

Explanation:

your welcome girlies <333

The concept illustrated in the flowchart is Natural selection. The correct option is 4.

What is natural selection?

Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.

Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.

Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.

Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.

These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.

Thus, the correct option is 4.

O B. DNA separates into two nuclei.

O C. The cell splits in two.

O D. Cytoplasm is manufactured.

Answers

Answer: A. Chromosomes are duplicated.

Explanation: This is the correct answer on the quiz.

Chromosomes are duplicated in S phase. Therefore, option (A) is correct.

What do you mean by S phase?

Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.

The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.

DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

Which means their adaptation methods will be different.

Natural selection is that the process through which populations of living organisms adapt and change.

What are the adaptations behavior in organisms?

Many animals are well adapted to biotic and abiotic conditions due to behavioral, physiological, or structural adaptations that increase their chances of survival and reproduction.

Behavioral - responses made by an organism that help it to survive/reproduce.

.

Physiological - a bodily process that helps an organism to survive/reproduce.

Structural - a feature of an organism’s body that helps it to survive/reproduce.

Select one:

b. diffusion and osmosis across semi-permeable membranes
c. the movement of the flagella of sperm for motility
d. exocytosis of waste substances across a semi-permeable membrane

Answers

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.

Answers

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.

The organism that is an animal-like protist is the amoeba.

What are amoebas?

Amoebas are a group of single-celled organisms belonging to the phylum Amoebozoa. They are classified as protists, which are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi.

Amoebas are characterized by their ability to move and change shape through the use of pseudopodia, which are temporary extensions of their cell membrane. These extensions allow amoebas to engulf and surround their food, typically consisting of bacteria, algae, or other small organisms.

Amoebas are single-celled protists that move using pseudopodia, which are temporary extensions of their cell membrane. They are classified as animal-like because of their ability to move and capture food in a similar manner to animals. Amoebas belong to the phylum Amoebozoa and are commonly found in freshwater and soil environments.
