Answer:

five-part radial symmetry

Explanation:

Echinoderms are non - chordates and mainly [present at the inner depth of the ocean. Echinoderms are deuterostomes, in which the anus develops first and mouth development takes place after the anus development.

Echinoderm animals do not live in freshwater or terrestrial (on land). The adults of the echinoderm can be easily identified by the five part- radial symmetry.

Thus, the correct answer is option (C).

A(n) _______ is an uncontrolled positive feedback loop between cytokines and leucocytes.
Vinvika [58]

Answer:

The given blank can be filled with cytokine storm.

Explanation:

Generally, influenza is self-restricting. Though serious cases can result in pneumonia and other issues, which can be deadly. However, such cases are very common in the elderly and in very young individuals. There are certain strains of the influenza virus, which are more dangerous to young adults in comparison to old or very young.  

The strains, which influence young adults are considered to comprise a cytokine storm, that is, a positive feedback loop, which produces in between the production of cytokines and leukocytes. This cytokine storm generates an acute inflammatory reaction, which results in brisk accumulation of fluid in the lungs, resulting in pulmonary failure. The very young or very old are less vulnerable to this influence as their immune systems are less strong.

Q2. Fill up:
Liono4ka [1.6K]

(a) The serum is the plasma without <u>clotting</u> factors.

(b) Phagocytic cells are <u>neutrophills</u> and monocytes.

(c) Eosinophils are linked with <u>allergic</u> reactions.

(d) In clotting, <u>calcium</u> ions play an important role.

(e) In an ECG, one can determine the heartbeat rate by counting the number of <u>QRS complex</u>.

<h3>EXPLANATION:</h3>

»» Blood without blood corpuscles is called plasma and plasma without clotting factors is called serum.

»» The professional phagocytes include many types of white blood cells (such as neutrophils, monocytes, macrophages, mast cells, and dendritic cells).

»» Eosinophils are associated with allergic reactions.

»» Calcium ions play a significant role in clotting.

»» When the cardiac rhythm is regular, the heart rate can be determined by the interval between two successive QRS complexes.

The trait of extraversion often correlates around 50% for identical twins and around _______ for fraternal twins.
tresset_1 [31]
The word extraversion is popularized by Carl Jung and defined it as "an attitude type characterized by concentration of interest on the external object (focuses on the outside world). Contemporary psychologists classified the dimensions of personality into five, which is referred to as the "BIG 5" personality traits. The BIG 5 are broad categories personality traits and though there are significant body of literature supporting this five-factor model personality, researches do not always agree on the exact labels for each. It will be helpful to remember the word OCEAN as an acronym for these "BIG 5" personality traits: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. Extraversion is one of the "BIG 5" personality traits an is characterized by excitability, sociability, talkativeness, assertiveness and high amount of emotional expressiveness. Extroverts are outgoing and gain energy in social situation. They tend to: enjoy being the center of attention because they get energized when they are around people, like to start conversations, enjoy meeting new people, have a wide social circle of friends and acquaintances because they find it easy to make friends and say things before they think about them. A published journal by Stephanie M. van den Berg, et al., entitled Harmonization of Neuroticism and Extraversion phenotypes across inventories and cohorts in the Genetic Personality Consortium: an application of Item Response Theory (IRT), studied on the heritability of extraversion in twins. The IRT-based scores for Neuroticism and extraversion were heritable, with 48 and 49% respectively, based on the meta-analysis of six twin cohorts with a significant part of the heritability due to non-additive genetic factors. For extraversion particularly, these genetic factors differ across sexes. So whether identical or fraternal, it correlates around 49-50% but will differ only across sexes, that is, whether male or female.
