The correct option is (A) Endoskeleton.

Endoskeleton is common between Echinoderms and chordata class.

<h3>What are the characterstics of Echinoderms?</h3>
  • They resemble stars and can be elongated or spherical. They only have spiky skin since they are aquatic organisms.
  • They exhibit organ system level organization and an open circulatory and digestive system. They have three lobes.
  • Their gills or the cloacal respiratory tree are how they breathe.
  • They have a simple radial nerve system and no excretory system. The body is unsegmented, with no discernible head.
  • Both asexual and sexual gametic fusion and regeneration occur during their sexual reproduction.
  • During indirect development, external fertilization takes place.
  • They are capable of regeneration.
  • Their sensory systems are not fully formed. Some of these include chemoreceptors, tactile organs, terminal tentacles, etc.

While taking a walk around the neighborhood, a student walks into a tree branch and cuts their arm. Which explanation BEST descr
DaniilM [7]

Answer:

C

Explanation:

First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!

Why is the karyotype for people with Turner syndrome written as 45XO
Kryger [21]

The number 45 means that the subject has 44 normal autosomal chromosomes (22 chromosomes pairs) plus one (1) good sex chromosome (out of the normal homologous pair). The X0 means that the subject, usually a female, lacks one sister chromosome of the homologous X chromosome pair, or has a partial X sister chromosome.

Which statement describes an event from the light-dependent stage of photosynthesis?
defon

The correct answer is option 4, that is, ATP and NADPH are produced.  

The light-dependent reactions refer to an array of biochemical reactions in the process of photosynthesis, which need light energy that is captivated by the light-absorbing pigments like chlorophyll. The light-dependent reactions occur in the thylakoid membranes of the chloroplast.  

The light-dependent reactions use energy in the form of light to produce two molecules required for the next phase of photosynthesis, that is, the energy storage molecule ATP and the reduced electron carrier NADPH.
