Sister chromatids are not bivalent and therefore cannot form tetrads. The synaptonemal complex is the fusion of the sister chrom

atids at the start of Meiosis I. If two chromosomes have similar positions, structures, and origins they are referred to as sister chromatids. Syanpsis is the fusion of chromosomes at the start of Meiosis I. A chiasma (or chiasmata) is the place where crossing over occurs. Crossing over is an event that occurs in Meiosis II and results in the exchange of genetic information between sister chromatids. 1) True 2) False

rewona [7]

Answer:

The process illustrated in the diagram is the non light dependent reactions of photosynthesis termed as Calvin Cycle.

Explanation:

  • Two molecules of 3-phosphoglycerate (3-PGA) are produced or released from step one to step two of Calvin cycle.
  • The source of energy that helps to start step one are ATP and NADPH, mainly derived from the light dependent reaction.
  • The oxygen molecule thus formed by splitting of water is release to the nature as oxygen, which living organisms utilizes in respiration.
  • Carbon dioxide comes from the atmosphere to start the process.
  • Light reactions occurs in the thylakoid membranes of the plant organelles namely chloroplasts.
  • Non-light dependent reaction or Calvin cycle takes place in the stroma chloroplasts.

A field has been left uncut for a year. Describe what it looks like at the end of one year and predict how it will be in five ye
Temka [501]

The vegetation is present in all parts of the field if it is left uncut for many years.

If a field has been left uncut for a year, the vegetation will grow to its highest point. But if the field is left uncut for five years and then in ten years, all the field is covered with dense vegetation including different types of plants.

The plants will grow and turn into shrub if they are not cut down. After 10 years the field looks like a forest with dense vegetative cover so we can conclude that all the field covered with vegetation if it is left uncut for many years.

Quiet metabolic activities account for about ________ of the average person’s daily energy expenditures
Valentin [98]

Quiet metabolism account for about 50% of the average person’s daily energy expenditures

A metabolism is a balancing act that involves two types of simultaneous activities: building up body tissues and energy stores (called anabolism) and breaking down body tissues and energy stores to get additional fuel for body functions (called catabolism)

Some of them are catabolic routes, such as glycolysis (the breaking of glucose), -oxidation (the breakdown of fatty acids), and amino acid catabolism. Others are anabolic pathways, such as those involved in energy storage (such as glycogenosis) and triglyceride synthesis (lipogenesis)

Metabolic pathways include the processes of producing and decomposing glucose molecules. A metabolic pathway is a chain of chemical reactions that feed off of one another.

Which features are created by deposition from rivers? Check all that apply. rills deltas floodplains alluvial fans oxbow lakes
algol13

The features which create deposition from rivers are found in food plains, alluvial fan, and deltas.

Deposition is termed as a process whereby the transported materials by a river are being deposited.

When a river losses energy we say that there is deposition.

Where there is high flow of water in a river deposition is likely to occur because more sediments are being carried as well as erosion which is being caused.
