Food webs with fewer species are more sensitive to the loss of species and ecosystem disturbances
Answer:
1. physical and chemical barriers
2.non-specific innate response
3. specific adaptive responses
Explanation:
Answer: She is involved in Taxonomy
Explanation:
What is Taxonomy?
Taxonomy is explained as the science of giving names, classifying and describing plants , animals and microorganisms.
A taxonomists will look at form, structure, behaviour and biochemical reactions in order to put species into their classification.
Answer:
Following Statements are true.
1. Cells receive molecular signals that communicate their position in relation to other cells.
3. Differential gene expression affects the developmental process in animals.
4. Positional information controls pattern formation.
6. Homeotic genes code for transcription factors that control the development of segment-specific body parts.
Explanation:
The formation of an eukaryotic organisms's spatial organization which includes organ formation and tissue arrangement is called as Pattern formation.
Molecular signals are received by cell. This phenomenon collectively refereed as positional information. Through this phenomenon cells are informed about their locomotion with respect to body axes and other cells. Regulation of pattern formation is controlled by Positional information.
When body axes is established a gene called homeotic gene start working as regulatory genes. This gene identify specific body segment in an organism which results in the formation of segment-specific body structures in the correct locations on the body.
Heart rate decreased suddenly and then MAP immediately fell because peripheral blood vessels were extensively vasodilated.
Explanation:
A VO2 max test is a clinical test done in a lab and is the ‘golden standard’ for measuring the potential and cardio-respiratory endurance of athletes and bikers.
It measures the oxygen carrying capability through a graded step test which determines the average power output. The maximal oxygen uptake along with cardiorespiratory responses is measured.
As per exercise physiology, the heart rate and cardiac output increases with exercise. When the potential is less, the resistance decreases, heart rate and mean arterial pressure also decrease
