Answer:

There is no way to produce tall offspring since both parents are homo-zygous recessive.

Explanation:

parent plants are short because neither of them has at least one dominant "S" gene. As both of them have recessive "s" genes, they are scientifically known as homo-zygous recessive organisms. So produced offspring will never be tall as they don't have the dominant "S" gene transmitted from their parents. this is genotypically expressed as below.

The two strands that make up the DNA double helix are said to be antiparallel. What does that mean?

Nucleotides containing adenine base pair with nucleotides containing thymine.

The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.

Base pairings create unequal spacing between the two DNA strands.

Answers

Answer:

The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.

Explanation:

Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).

The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

How is cross pollination carried out in nature?
A, B, or C?

Answers

OPTION B is the correct answer

Cross-pollination is carried out by bees and other pollinators, which is present in option B, as cross-pollination is a process in which pollen from the male reproductive organs of a plant (such as the stamen) is transferred to the female reproductive organs.

Cross-pollination is facilitated by various agents, including insects, birds, wind, and even water. These agents inadvertently carry pollen from one plant to another as they move between flowers or plants. Insect pollinators, such as bees, butterflies, and beetles, are the most common and efficient carriers of pollen in cross-pollination. They visit flowers to obtain nectar or pollen as a food source, and in the process, pollen grains get attached to their bodies and are transported to other flowers.

6. The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles,
and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local
ecosystems?
A. The variety of interactions among the different species helps the ecosystems remain
sustainable.
B. The variety of interactions among the different species prevents the ecosystems from being
sustainable.
C. The uniformity of interactions among the different species prevents the ecosystems from
being sustainable.
D. The uniformity of interactions among the different species helps the ecosystems remain
sustainable.

Answers

Answer:

A.

Explanation:

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

The DNA structures of prokaryotic and eukaryotic cells share similarities and differences. One way in which they are the same is that
A. both have sugar-phosphate backbones
B most of the DNA is in the form of plasmids
C both have a singular circular chromosome
D the DNA is packaged into several linear pieces

Answers

One way in which the DNA structures of prokaryotic and eukaryotic cells are similar is that both have sugar-phosphate backbones.

The DNAs of all living organisms, be it prokaryotes or eukaryotes, are similar and consists of 3 major chemical groups:

5-carbon deoxyribose sugarsnitrogenous purine or pyrimidine basesphosphate group

The pentose deoxyribose sugar and the phosphate group form the backbone of the structure of DNA. The sugars are linked together by phosphodiester bonds formed between the carbon 4 of each sugar and the methyl group attached to the phosphate.

The similarity in the structure of DNA of all living organisms is one evidence being used to support the evolution of living organisms from a common ancestor.

How HACCP system works?

HACCP : hazard analysis critical control point.

It is a management system that addresses food safety through analysis and control of biological, physical and chemical hazard.

There is a working flow of HACCP that ensures food safety begins from raw material production, procurement, handling, to manufacturing, distribution and consumption of the finished food product.

Hence, it can be said that HACCP system begins when food is delivered to the store and served to the guest that is consumption of the final product.

Answers

Answer:

If you mean the complementary strand of GAT: Answer is CTA

If you mean the strand for all of it (GATCCATGAGTTACG): Answer is CTAGGTACTCAATGC

Explanation:

Both strands always have to be in a sequence that pairs them to their nitrogenous base pair according to Chargaff's law. So always remember:

A pairs with T (Adenine with Thymine)

C pairs with G (Cytosine with Guanine)

Whenever you need to figure out the other strand, just switch the original base sequence with their base pairs to get the second strand/sequence.
