Anyone? need a teacher or student who is really good at science

Answer: D) chromosomes and genes

Chromosomes are long thread like structures which are found inside the nucleus of the living organisms. These chromosomes consists of small segment units called as genes. The genes control the genetic information which when expresses result in the production of specialized functional proteins. The gene is a hereditary material which is passed from the parents to the offsprings after reproduction. The expression of genes in the new organisms results in the expression of characters which were found to be similar in both parents and offsprings but some changes occur due genetic variation. Therefore, organisms exhibit anatomical similarities in features due to chromosomes and genes.  

Chromosomes and genes determines the similarities in anatomical features among organisms. The correct option is D.

Thus, Chromosomes, which resemble lengthy threads, are found inside the nucleus of living things. The little segment units that make up these chromosomes are known as genes.

The genes regulate the genetic material, which, when expressed, leads to the creation of certain, useful proteins. The gene is a genetic component that, during reproduction, is transferred from parents to children.

Characters that were determined to be comparable in both parents and children are expressed by genes in new creatures, however some modifications take place owing to genetic diversity. The correct option is D.

Answer: to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.

Explanation:

Answer:

Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization. For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.

Answer:

answer, I guess, is C.primary succession

Answer:

A

Explanation:

Isostatic equilibrium is used to state why some regions of the lithosphere have greater elevation than others. The crust ‘floats’on the‘liquid’ mantle below and different regions  of the crust submerge into the mantle differentially depending on their local densities or weight. Heavier regions such as in mountainous region (like the Himalayas) are sunken deeper into the mantle that other regions.  Every local region has its own local isostatic equilibrium.

Answer:

The correct option is Option C

i.e. Asthenosphere is denser than lithosphere.

Explanation:

Asthenosphere is the layer situated below the lithosphere.

Theory of isostasy says that the layers above the other layer must have lesser density. This has two explanations. Firstly, if its not hold, then the denser above layer would sink below the less denser bottom layer. Secondly, as we go inwards, the pressure increases. This leads to the lower layers have greater density. So, as Asthenosphere is situated below the lithosphere, it has higher density.
