A forest usually,to hide behind the leaves or to sty away from predators.
Answer:
- 25 tall individuals, TT
- 50 medium individuals, Tt
- 25 short individuals, tt
Explanation:
<u>Available data</u>:
- The size of this species was determined by a single gene
- TT- Tall
- Tt- Medium
- tt- Short
- Total number of individuals in the progeny, N = 100
There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.
Cross: between two medium Gazorps
Parentals) Tt x Tt
Gametes) T t T t
Punnett square) T t
T TT Tt
t tT tt
F1) 1/4 = 25% TT, tall
2/4 = 1/2 = 50% Tt, medium
1/4 = 25% tt, short
100% of the progeny ------------ 100 individuals
25% Tall, TT ------------------------X = 25 individuals
50% Medium, Tt -------------------X = 50 individuals
25% Short, tt ------------------------X = 25 individuals
Answer:
Explanation:
A cell as the functional and structural unit of life exhibits numerous concepts of life which include:
1. Growth; A cell is a subject to this as the growth of a cell translates to the growth of the tissue is composed of, the cell is responsible for all biochemical actions in living organisms, this growth is achieved via mitosis.
2. Reproduction: Cells also experience reproduction via meiosis, where a diploid cell divides to produce 2haploid cells an example of this is the spermatozoa.
3. Death: Cells are also subject to death, which can either be programmed (Apoptosis), or due to sickness(Necrosis). This is also found when humans die and become stiff due to rigor mortis which occurs as a result of cell death
Answer:
a. In Left gaze bias experiment, scientists tested to see if dogs portrayed left gaze bias like humans when presented with pictures of human or dog faces.
b. The left gaze bias looks at the right side of ones face at first site and dogs do this with humans but not other dogs.
c. With the encounter with other human faces, humans look at each other with left gaze bias.
d. The scientist were testing if the dogs recognize expression regarding direction of gaze same as human.
The correct answer is an ecosystem.
An ecosystem refers to the community comprising of living species and non-living constituents, like water, air, and mineral soil. The ecosystems involve associations among the species, and amongst the species and their surroundings.
In ecology, a community refers to an association or group of populations of two or more distinct species occupying the similar geographical region and in a specific time, also called biocoenosis.
