First image is the double helix and the second one is chromosome.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division.
Chromosomes are arranged in ordered haploid sets around the centre of the metaphase plate at mitosis in several grass species and hybrids.

Which class of protozoa shows nuclear dimorphism:
Answer:
Protozoan Tetrahymena
hope it helps!
Protozoa are eukaryotic organisms that are single-celled and free-living. Paramecium and Tetrahymena are the members of the ciliated class of Protozoan showing nuclear dimorphism.
What are Protozoa?Protozoans has been defined as unicellular eukaryote that is either parasitic or free-living. Ciliate is one of the classes of Protozoans that are characterized by the presence of cilia on the outer surface of the body.
The genus Paramecium and Tetrahymena of ciliated Protozoans show nuclear dimorphism as they have two different types of nuclei in their cell. One of the nuclei is somatic and the other is germline.
This property of nuclear dimorphism is seen in the lower organism like the Protozoans that needs a micronucleus for reproduction and the other macronucleus for the functioning and regulating of the cell. This property of the Protozoans makes them different from the other eukaryotes that possess only a single nucleus in their cell.
Therefore, the ciliated class of Protozoans shows nuclear dimorphism.

What are the two most important driving forces of metamorphism?
A. High heat and pressure
B. Melting and cystallization
C. Deposition and lithification
D.Weathering and accumulation
E.Magma and lava
ne questions
Answer:
Heat and pressure
Explanation:
Metamorphic rocks are found deep underground
The two most important driving forces of metamorphism are high heat and pressure (option A).
These two factors play a significant role in transforming rocks into metamorphic rocks. When rocks are subjected to high temperatures and pressures, the minerals within them undergo changes in their composition, structure, and texture. This process leads to the formation of new minerals and the recrystallization of existing minerals, resulting in the development of distinct metamorphic textures and structures.
The course of transformation doesn't dissolve the stones, however rather changes them into denser, more conservative rocks. Rearrangements of mineral components or reactions with fluids that enter the rocks produce new minerals.

A. A line that goes up and down
B. An increasing line
C. A decreasing line
D. A flat line
Answer:
A decreasing line
Explanation:
The graph of carbon dioxide absorption look like a decreasing line for the forested area. Thus, the correct option will be C.
What is Carbon dioxide absorption?The absorption of carbon dioxide gas is an important process in many of the practical applications such as the reduction of greenhouse gases, separation as well as the purification processes in the chemical and the petroleum industries, and it also involve capturing of the radioactive isotopes in the nuclear fuel cycle and environment.
The carbon dioxide gas is captured and it can be put to the productive use in enhanced oil recovery as well as the manufacture of fossil fuels, building materials, and more, or it can be stored in the underground geologic formations in the environment.

Which statement BEST describes the effect of human urbanization on biodiversity in the Amazon
rainforest?
A
Human urbanization increases biodiversity because cleared land attracts more
species into an area
B
Human urbanization decreases biodiversity because habitats and resources are
lost to native species
С
Human urbanization increases biodiversity because of non-native species
introduced to the food web.
D
Human urbanization decreases biodiversity because limiting factors of the forest
ecosystem are reduced.
Human urbanization would generally decrease the biodiversity of any forest because habitats and resources are lost during the process of urbanization.
Urbanization refers to the process through which cities are created out of urban areas.Cities are created by removing vegetation and erecting infrastructures such as buildings, roads, bridges, etc. The removal of vegetation means that habitats of organisms would be lost as well as the biodiversity that constitutes the vegetation itself.Thus, urbanization would automatically lead to a loss of biodiversity in the Amazon forest.

Mitosis produces which cell type?
haploid
diploid
chromosome
gamete
Answer:
b, diploid.
Explanation:
Mitosis produces two diploid somatic cells, genetically identical to each other and the parent cell.
Mitosis produces diploid cells (option B)
What is Mitosis?Mitosis is a process of cell division observed in cells. Its primary purpose is to ensure that the genetic information, in the parent cell is equally distributed among the resulting daughter cells.
During mitosis the process generates cells that are diploid, meaning that the number of chromosomes in the parent cell is the same as the number in the resulting daughter cells.
In contrast haploid cells have half the number of chromosomes found in cells. Examples of haploid cells include sperm and eggs which are known as gametes.
Notably, we can conclude that mitosis produces diploid cells (option B)

An essential characteristic of the members of a given species is the ability to reproduce with one another and have fertile offspring. Thus, the correct option is C.
What are the characteristics of a species?A species is a group of organisms which are living in an area with similar characteristics which are capable of exchanging genes and chromosomes and produce new organism similar to itself. The species are important as it maintains the equilibrium in the ecosystem.
A species can be defined as the largest group of organisms with the two individuals of the appropriate sexes can produce a fertile offspring, typically through sexual reproduction. The species can also be defined on the basis of their karyotype, DNA sequence, morphology, behavior or ecological niche.

How does heart rate affect blood pressure
Answer:
Does heart rate affect blood pressure?
A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily. When you exercise, your heart speeds up so more blood can reach your muscles.
Explanation:
Answer: As your heart beats faster, healthy blood vessels will expand in size to allow increased blood flow, which helps your blood pressure remain relatively stable.
