Answer:
They concluded that DNA is a genetic material.
Explanation:
This experiment shows that the DNA is genetic material. For performing experiments, the DNA of bacteriophages is labelled with radioactive phosphorous (32P) and proteins were labelled with sulfur (35S) in order to detect the action of bacteriophages. The bacteriophages attack on the bacteria by inserting its DNA in the bacteria. We can see this because radioactive phosphorus is present in DNA of bacteriophages while the protein did not enter into the bacteria and remain outside the cell and we can see it because protein is made up of sulphur.

What are the characteristics of gene ?A gene is physical and functional unit of heredity which is made up of DNA.
Genes control both DNA and RNA function.
Some genes codes protein for functional expression of a trait where as some genes do not code for proteins.
In humans, the size of genes ranges from few hundred DNA bases to more than 2 million bases and human have between 20,000 and 25,000 genes.
Each gene have two copies, one is passed from each parent. Only 1 percent of the total genes is slightly different between people.
This is because of presence two different types of allele the same gene which contribute to each person’s unique physical features.

The given image is a neuron. Neurons are present in the nervous system. The part which is labelled as 4 in the diagram is myelin sheath. Thus, the correct option is D.
What is a Nerve cell?A nerve cell is a specialized cell which makes the nervous system. This system is responsible for the control of functions in an organism. Neuron (nerve cell) are the basic units of the nervous system.
A nerve cell consists of three parts- the cell body, a major branching fiber which is an axon and smaller branching fibers known as dendrites. The axon has nodes of Ranvier and myelin sheath. The nodes of Ranvier are the gaps which are present in the myelin sheath that coats the neural axon. The myelin sheath permits electrical impulse to move down the axon in a neuron. The nodes of Ranvier allow movement of ions in and out of the neuron that helps in propagation of electrical signals down the axon of the nerve cell.
Therefore, the correct option is D.

What connection do all living things have with each another
Answers
Answer:
they all have cells
Explanation:
each living thing has cells that help them survive and help their body work well.
Answer:
All organisms need food for the energy required to live and grow. They all excrete (get rid of) waste products, and detect changes in their surroundings and respond to them. All living organisms follow a LIFE CYCLE of growth and development, reproduction, and death. One thing all living things have in common is that all living things have cells, performing the functions necessary for an organism to survive in its environment; even the most primitive of life forms, bacteria, consists of a single cell. All living things also use energy, grow and reproduce.
Why do droughts contribute to desertification?
Answers
Answer:
Drought and desertification are firmly related phenomenon. Continuing over months or years, drought can influence enormous zones and may have genuine ecological, social and financial effects.
While drought is a characteristic phenomenon, whose effects can be exacerbated by human exercises that are not adjusted to the neighborhood atmosphere, land debasement is the way toward transforming fruitful land into less or non-gainful land. In extraordinary cases in drylands this is called desertification.
Land debasement and desertification are complex phenomenon driven by un-adjusted human action in mix with land and climatic requirements. Improper land use, for example, monocultures, and unreasonable land the board rehearses, for example, deforestation, unsatisfactory agrarian practices and overexploitation of water assets), can cause land debasement that can be additionally disturbed by drought.

O C. Sea levels rose over 300 feet.
D. Land bridges existed that are now underwater.
Answers
The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.

Which two organisms are most closely related, based on the tree above? ray-finned fishes and sharks rodents and primates dinosaurs and crocodiles dinosaurs and birds
Answers
Answer:
dinosaurs and birds
Explanation:
Dinosaurs and birds are considered as the most closely related species to one another because they are evolved from a common ancestor. They show resemblance in many ways such as physical structure, both dinosaurs and birds moves on two feets etc. In phylogenetic tree, dinosaurs and birds are the roots from which other organism evolved. So that's why dinosaurs and birds are considered the most closely related species living on earth.
The organisms that are most closely related (based on the tree above described) are dinosaurs and birds.
Evolution and phylogenetic treesEvolution refers to the natural process of descendence with modification, which is mainly due to natural selection.
Evolution leads to speciation, thereby species are related and they show evolutionary relationships.A phylogenetic tree is a diagram that represents evolutionary relationships between species that share a common ancestor.In conclusion, the organisms that are most closely related (based on the tree above described) are dinosaurs and birds.

Water moves from higher concentration of salt molecules across a semi-permeable membrane to lower concentration of salt molecules. d. Both b and c e. Both a and c
Answers
Answer:
a. Water moves from an area of high concentration of water molecules across a semi-permeable membrane to an area of lower concentration of water molecules.
Explanation:
Osmosis is a physical phenomenon in which solvent molecules move through a semi-permeable membrane from a region with low solute molecules concentration to a region with high solute molecules concentration. Or in order word, osmosis is the flow of solvent molecules (example is water) through a semi permeable membrane, from a region of higher concentration, to a region of lower concentration of water molecules. Example of osmosis is the biological flow of water molecules into or out of the body cells through the cell walls, in response to the difference in the concentration of salts and minerals within and outside the cell wall.
The number of chromosomes during meiosis is incredibly important.why is that?
Answers
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.
I hope this helps you
Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.
Why the number of chromosomes is important during meiosis?Meiosis is a eukaryotic cell division process. However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.
Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.
