A stem is what keeps the plant together and supports their leaves
B. STEMS
Phylogeny
uses communal ancestry to group organisms and further nest them into bigger and
bigger groups. This is also a study of evolutionary relationships among
organisms. Visible characteristics such as anatomical and behavioral traits, as
well as biochemical (enzymes, proteins, pigments, etc.) and genetic traits
(nucleotide sequences) that need more modern techniques to detect.
Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
Answer:
Commensalism
Explanation:
Commensalism is a relationship between species in which one benefits and the other is unaffected. Humans are host to a variety of commensal bacteria in their bodies that do not harm them but rely on them for survival
Answer:
a. Glycolysis
b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration
c. Heart tissue!
Explanation:
a. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.
b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.
c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.
Hope this helps! If you could, please mark this as brainliest :)
