I believe in both groups , the sperm swim from antheridia to aronia. Both are tied to water by swimming sperm that require water to reach eggs. Neither of them has pollen, seeds, flowers, or fruits. Seedless vascular plants, however, have xylem and phloem, which bryophytes lack. For seedless vascular plants Cells in diploid sporophyte such as fern from undergo meiosis, releasing haploid spores that germinate and develop into gametophytes. Bryophytes reproduce sexually by forming sperm and egg cells within separate haploid male and female gametophytes.
Answer:
Homologous structures provide evidence for common ancestry analogous structures show that similar selective pressures can produce similar adaptations beneficial features Similarities and differences among biological molecules in the DNA sequence of genes can be used to determine species relatedness
1) Both involve electron transport chains.
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
Answer:
Enzyme- Peptidase/protease
Explanation:
According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.
This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.
However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.
