Describe how radio telescopes are used to explore space.

Answers

Answer 1

Answer:

A radio telescope is a form of radio receiver used in astronomy. In contrast to an "ordinary" telescope, which receives visible light, a radio telescope sees radio waves emitted by radio sources, typically by means of a large parabolic (or a "dish") antenna, or arrays of them.

Which protist exhibits both animal-like and plant-like characteristics?
a protist that has pseudopods and swims by using cilia
a protist that makes its own food and has glass-like cell walls
a protist that is a heterotroph and has chlorophyll
O a protist that can move or be stationary

Answers

Hi there!

I think the answer would be a protist that is a heterotroph and has chlorophyll. The protist falling under this category is called Euglena. Euglena has the ability to synthesize food using its chlorophyll, but if the light gets scarce it can utilize its heterotroph qualities and catch food instead.

implantation of embryo take

in the uterus.​

Answers

Answer:

Implantation is the mechanism by which a blastocyst, which is passing through the uterus as a developing embryo, makes contact with the uterine wall and remains bound to it before birth. The uterine lining (endometrium) undergoes several internal modifications in order to allow for the emerging blastocyst to bind to it.

- Cyanide is a strong cytochrome c oxidase inhibitor. Cytochrome c is the last enzyme in the
electron transport chain. If cell is exposed to cyanide, most of the cyanide will be found in which
of the organelles?​

Answers

Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.

Fossils can be body parts of ancient organisms, or they can be traces. Give five examples of trace fossils

Answers

Answer:  

Trackways/footprints, mold and cast fossils, feeding marks, coprolites, and burrows. Trace fossils show the activity of ancient organisms rather than the body fossil itself. However, it is rather difficult to identify an organism by use of mere trace fossil, and therefore, it is less accurate.

Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence. I. Pathogen is destroyed and digested and parts are presented. II. Lymphocytes secrete antibodies. III. Antigens from pathogens bind to matching receptors on lymphocytes. IV. Lymphocytes specific to a pathogen's antigens become numerous. V. Only memory cells remain.

Answers

Answer:

The correct sequence is:III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.

II) Lymphocytes secrete antibodies.

I) Pathogen is destroyed.

V) Only memory cells remain.

Explanation:

Effective resistance against infection is essential for the development and functioning of the mammalian organism, and for it to be effective, multiple defense systems must be available. In order to meet these objectives, the body has developed a complex system of overlapping and interrelated defense mechanisms, which together can destroy or control almost all invaders.III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. It consists of the binding of the foreign antigen to the specific receptors existing on the membrane of mature lymphocytes. The B lymphocytes that mediate humoral immunity express antibody molecules on their surface, which bind to foreign proteins, polysaccharides or lipids in their soluble form; T lymphocytes, responsible for cellular immunity, express so-called T cell receptors (TCR), which recognize small sequences of antigenic peptides.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.II) Lymphocytes secrete antibodies.

Activation phase: sequence of events that occur in lymphocytes as a result of specific antigen recognition. All lymphocytes undergo two fundamental changes: a) proliferation: expansion of antigen-specific clones and amplification of the protective response, in which the CD4 T lymphocyte, capable of activating CD8 B and T lymphocytes, assumes a preponderant role; b) differentiation: stage in which effector cells and memory cells are formed. The first produce various substances that can interact with the antigen, such as antibodies and lymphokines; the second are partially differentiated lymphocytes, that is, they do not become effector cells.

I) Pathogen is destroyed.

In this phase, the T lymphocytes differentiated into effector cells migrate to the sites of attack, where they carry out their functions of eliminating pathogens, while the B lymphocytes perform them in the peripheral organs themselves.

V) Only memory cells remain.

One of the most important consequences of the adaptive immune response is the establishment of the state of immunological memory, which lies in the ability of the immune system to respond more quickly and efficiently to microorganisms that have previously infected the host and it reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. We call, therefore, the immune response that the organism gives when it comes into contact for the first time with a foreign agent and from which a series of events derives that include nonspecific innate defense mechanisms and adaptive response mechanisms, if the pathogen manages to survive the first ones.
