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
.
A branch point on a phylogenetic tree is a separation point, from where a lineage is evolved into a new different lineage. The basal taxon is the unbranched lineages which evolved from the root.
The question is incomplete as figure is missing which is attached.
Answer:
C) 70 Kcal
Explanation:
In a food chain, the energy is transferred from one trophic level to another trophic level following a mathematical law given by Lindeman called ten per cent law which states that only 10% of the total energy is transferred from one trophic level to another level.
In the given question since the shepherd is considered the secondary consumer or the third level which feeds on the primary consumer therefore by ten per cent law, the primary consumer receives only 70 kcal and the secondary consumers that are sheepshead receive only 7kcal.
Thus, C) 70 Kcal is the correct answer.
Answer:
Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.
Explanation:
Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug
, housefly, butterfly and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.
