The answer you chose is correct becAuse if both parents are heterozygous for a disease that is recessive there is a 25%chance of the offspring inheriting the trait.Ex:
R r
R (RR) (Rr)
r (Rr) (rr) rr is the only outcome that can inherit the disease.
Answer:
We can determine the past arrangement of leaves on a bare twig by looking at the arrangement of axillary buds and leaf scars.
Explanation:
- The arrangement of leaves on a branch or stem is called phyllotaxy.
- Leaves are formed at stem nodes.
- They bear axillary bud on their axil.
- Axillary bud give rise to flowers and new branches.
- When leaves shred off we can determine their phyllotaxy by looking at the axillary buds on the nodes.
- When leaves fall off the stem, they leave scars at the nodes, these scars can also be considered to find out the attachment of leaves and phyllotaxy.
Common leaf arrangements are:
- Alternate.- When one leaf arises at each node and successive leaves develop on alternate sides .se.g. As seen in Barberry
- Opposite- When two leaves arise at one node and on the opposite side of the stem. E.g as seen in maple.
- Whorled.- When three or more leaves arise at a node forming a whorl.
Answer:
The correct answer will be amino acids.
Explanation:
The process of protein synthesis takes place in an organelle called ribosomes. The ribosome reads the information coded in the mRNA in the form of triplets of nitrogenous bases also known as "codons". The codons code for specific amino acids which are assembled or joined via peptide bonds in the ribosomes.
In the question, Katie wanted to make doghouse of the wood and nails in which if doghouse represents the protein, the nails and wood will represent the basic unit or monomer of a protein called amino acids which are put together by a hammer.
Thus, amino acids are the correct answer.
Answer:
The direct conversion of mesenchymal tissue into bone is called i<u><em>ntramembranous ossification</em></u> .The process by which a cartilage intermediate is formed and replaced by bone cells is called <em>endochondral osssification.</em>
Explanation:
Intramembranous ossification is one of the two essential process during the fetal development of the gnathosome skeltal system by which rudimentary bone tissue is created. It is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, mandible and the clavicle. This type of ossification also helps in healing of bone fractures.
Endochondral Osssification: Method of forming a bone through cartilage intermediate. It is also involved in the formation of long bones.
