Answer:
Cc
Explanation:
A cleft chin is an example of a trait that is controlled by genetics. A cleft chin is when there is a dimple in the chin which arises when the two sides of the jaw don’t completely fuse together. Famous people with cleft chins are Henry Cavill, John Travolta and Niall Horan.
A cleft chin is generally thought to be a dominant trait. That means, if an individual carries one copy of the cleft chin gene (heterozygous), then they will display the trait.
There are three options: an individual can be homozygous dominant (CC), homozygous recessive (cc) or heterozygous (Cc). A heterozygous person will always have 2 different alleles (for any trait, not just cleft chin). In this case, a heterozygous person will have a cleft chin, because it is dominant. Therefore, an heterozygous person with a cleft chin will be Cc
Remember, the letter doesn't matter - they could also be denoted as Bb, Qq, Rr, Ff. The letter is arbitrary.
Answer:
A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
You have ligaments around your knees, ankles, elbows, shoulders, and all of your other joints.
Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. Ligaments are made out of connective tissue that has a lot of strong collagen fibers in it. They are found in different shapes and sizes in the body. Some look like pieces of string, others look like narrow or wide bands. There are arch-shaped ligaments, too.
Explanation:
Answer:
facilitated diffusion
Explanation:
Facilitated diffusion is the process of movement of molecules or ions across a biological membrane via specific transmembrane integral proteins. Carrier proteins and channel proteins are involved in facilitated diffusion. The movement of molecules and ions in passive transport occurs due to a concentration gradient.
A
. Leaves were trapped between layers of sediment millions of years ago, causing the imprint
Explanation:
The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.
Leaf imprints are often referred to as trace fossils.
- Trace fossils points to the different life activities an organism must have been engaged in.
- When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
- This gives a physical overview to the nature of leaf.
- Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
- Option C is completely wrong
