what is the difference between ribose and deoxyribose

Answers

Answer: Ribose is a pentose sugar and is found in DNA. Ribose binds a phosphate at the 3′ position

Ribose is a 5-carbon simple sugar. The chemical formula of this sugar molecule is H−(C=O)−(CHOH)4−H. This is the prime component of ribonucleic acid strands. It forms ribonucleotides.


Deoxyribose is a hexose sugar and is found in RNA. Deoxyribose binds a phosphate at the 2′ position. deoxyribose has one less oxygen molecule than ribose.

Deoxyribose, on the other hand, is a monosaccharide too. It also has the same 5-carbon formula as that of ribose sugar but loses an oxygen atom. Its chemical formula is H−(C=O)−(CH2)−(CHOH)3−H

All of the following among A-D apply to toll-like receptors EXCEPT A. they bind to PAMPS B. they induce the release of cytokines when activated C. they directly lyse bound pathogens D. when stimulated, they activate the immune system of the body E. there are no exceptions, A-D are all true

Answers

The toll-like receptors do NOT directly lyse bound pathogens (Option C). These protein receptors play fundamental roles in the innate immune system.

Toll-like receptors (TLRs) are single-pass membrane-spanning protein receptors that play fundamental functions in the innate immune system.

TLRs are differentially expressed on the surface of antigen-presenting cells (i.e., macrophages and dendritic cells) in order to recognize evolutionary conserved antigenic domains in different pathogenic microorganisms (e.g. bacteria).

TLRs initiate innate immune responses such as, for example, inflammatory responses, by identifying conserved pathogen-associated molecule patterns (PAMPs).

According to the food chain shown, about how much energy from the grasshopper trophic level is transferred to the frog trophic level?

Answers

The amount of energy transferred to frog   is 10% of the energy contained in grasshopper.

This is a representation of energy levels and distribution in a food chain in an Ecosystem. When a group of organism  represent the same level in a food chain, in an ecosystem ,this is trophic level. Food chain represent a linear representation of nutrients and  therefore energy distributions in an ecosystem.

Basically, in an ecosystem, there is always reduction in energy transfer from one trophic level to another by 10%. This is because, as the energy is transferred from the producer (green plants) to the primary consumer, the hopper, only 10% of the available energy will pass through to the hopper because 90% of the energy will be used by the green plants for metabolic and other physiologic  activities.  As this is transferred to the next trophic level, the Frog, this will be  reduced (for the same reasons) so that  10% of the energy received by the grasshopper is transferred to the frog.

Practically, if 100,000Kcal of energy was obtained by hopper from the primary producer,10,000kcal(10%) of 100,000 will be transferred to frog.

This 10% occurs at each trophic levels.

Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be

Answers

Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY.  This theory is not now accepted.

Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.

Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.

Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.
