Which of the following is TRUE about what occurs in the chemical reaction of cellular respiration? CHOOSE ALL THAT APPLY. Questi

on 4 options: Energy is both transformed and spent in the steps of cellular respiration, but overall there is a net gain. The reactions within cellular respiration are both aerobic and anaerobic Energy from the sun is converted in to sugars. Law of conservation of matter and energy is followed. There are more inputs than there are outputs. Save

Thank you for posting your question here at brainly. I think the true statement about what occurs in the chemical reaction of cellular respiration is "The reactions within cellular respiration are both aerobic and anaerobic Energy from the sun is converted in to sugars."

Krill in this food web is the primary consumer. Since the producer of the food web is the phytoplankton. Removing them from the food chain cuts the supply of food for secondary consumers such as seals, and whales. This disrupts the whole Antartic ecosystem since there will be a large amount of phytoplankton but not enough food for secondary consumers. This because secondary consumers are not able to eat phytoplankton due to their microscopic size. Only krill are able to feed on them and have the maximum energy gain from them.

Meiosis Foldable Activity 515.2
Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

  • homologs pair off into bivalents
  • At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I  forming bivalents; tetrads are formed.
  • Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
  • then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

  • Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
  • independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
  • in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
  • Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

True or false: Most muscles contain a combination of all three muscle types, slow oxidative, fast oxidative, and fast glycolytic
kkurt [141]

Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.

Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:

  1. Cardiac muscle
  2. Skeletal muscle
  3. Smooth muscle

Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:

  1. Slow oxidative
  2. Fast oxidative
  3. Fast glycolytic.
