Answer:
a shared derived trait.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.
All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.
This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.
A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.
Answer:
The answer is the first option. The trailing edge is composed of many filopodia containing tight parallel bundles. These filopodia push trailing edge away from the location it was previously occupying.
Explanation:
Cells migrating in tissues exhibit both filopodia and lamellipodia. These thin protrusive extensions are ideal for exploring and penetrating tissue spaces. They are also well suited for intercalating between cells, such as during the migration of leukocytes across endothelial layers.
Therefore the answer is the first option.
The world's population is projected to be 9.7 billion by 2050
Option:
a.) gain of meiosis
.
b.) loss of mobility.
c.) loss of chloroplasts
.
d.) no changes would be expected
.
e.) gain a rigid cell wall.
Answer:
- <u>Option-(C):</u> Loss of chloroplasts
.
Explanation:
- The protists are known to have the chloroplast inside there bodies in order to have there own food mostly prepared by themselves in the given manner, since they no more require the chloroplast to produce there own food thus the presence of the pigment will no use to them. And thus after the level of evolution that occurs inside them we do not expect any form of pigments to be found inside there bodies.
