Answer:

The correct characteristics are -<em><u> tissue, coelom, segmentation, endoskeleton, and backbone</u></em> from top to bottom boxes.

Explanation:

This phylogenetic tree showing the evolution and relatedness of the different organisms on their shared characteristics. In the given phylogenetic tree there are some characters are missing and we can predict or state them on the basis of evolution and studying the characteristics.

After the Porifera phylum tissue-level organization is found in the organism hence Tissue would be placed in the first box.

The coelom is found organisms above the Nematoda level, which further include a character segmentation in Annelida and Arthropoda. Another lineage from arising with the coelom organism that included endoskelton and backbone.

Thus, The correct characteristics are - tissue, coelom, segmentation, endoskeleton, and backbone from top to bottom boxes.

Name and describe all of the weather fronts.
Yakvenalex [24]

Answer:

four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

a air front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.

A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.

Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.

Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm

Why is a 50 percent recovery of single-crossover products the upper limit, even when crossing over always occurs between two lin
34kurt

Answer:

Because of homologous recombination

Explanation:

  • When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.
  • When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.
  • We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.
  • Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.

  • When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.
  • When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked

Which of the following describes prophase of mitosis?
tigry1 [53]

Answer:

Daughter chromosomes move toward opposite poles of the cell.

Explanation:

Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.

CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.

When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.

1. Distinguish between physical and chemical changes. Include examples in your explanations.
Rashid [163]

Answer:

Physical change

Any change to the physical properties of a substance is called a physical change.

Physical changes are usually reversible as no new substance is formed. It is the same substance but with changed physical properties.

Chemical change

A change in which one or more new substances are formed is called as a chemical change.

Usually a chemical change involves a chemical reaction, which forms new products.

Example : Rusting of Iron, or burning wood.
