Answer: it is c, a covalent bond
Explanation:
Answer:
C
Explanation:
Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
Long-term potentiation (LTP) is considered a cellular correlate of learning and memory. The presence of G protein-activated inwardly rectifying K(+) (GIRK) channels near excitatory synapses on dendritic spines suggests their possible involvement in synaptic plasticity. However, whether activity-dependent regulation of channels affects excitatory synaptic plasticity is unknown. In a companion article we have reported activity-dependent regulation of GIRK channel density in cultured hippocampal neurons that requires activity oF receptors (NMDAR) and protein phosphatase-1 (PP1) and takes place within 15 min. In this study, we performed whole-cell recordings of cultured hippocampal neurons and found that NMDAR activation increases basal GIRK current and GIRK channel activation mediated by adenosine A(1) receptors, but not GABA(B) receptors. Given the similar involvement of NMDARs, adenosine receptors, and PP1 in depotentiation of LTP caused by low-frequency stimulation that immediately follows LTP-inducing high-frequency stimulation, we wondered whether NMDAR-induced increase in GIRK channel surface density and current may contribute to the molecular mechanisms underlying this specific depotentiation. Remarkably, GIRK2 null mutation or GIRK channel blockade abolishes depotentiation of LTP, demonstrating that GIRK channels are critical for depotentiation, one form of excitatory synaptic plasticity.

Uhh-
Explanation:
Bruh there's no pic so ... I dunno lol. Just in case this helps you, hypothesis means an educated guess. There's different meanings, for science it's an idea. But mostly it means guessing.
I didn't help Ik XD
And
Sorry
I
Couldn't
Helppp

Answer:
D. stabilizes the position of the kidneys by holding them in their normal position
Explanation:
Adipose tissue is a type of connective tissue and is therefore called by some adipose connective tissue. As we saw in the article “Connective Tissue Cells”, adipose tissue is made up of adipose cells, also called adipocytes. Fat tissue specializes in fat storage and is found well below the skin.
Some of our internal organs like kidneys and heart have a layer of adipose tissue lining them. This layer of fat around the organs gives them greater protection against mechanical shock. In addition, in the kidneys, adipose tissue fills the voids between other tissues and helps keep these organs in their normal positions.
