Compare an animal with a gastrovascular cavity to an animal with a tube-type digestive system. What is(are) the major advantage(
bonufazy [111]

Answer:

hello your question lacks the required options

Group of answer choices

It allows the animal to consume a second meal while the first is being digested.

It permits development of specialized enzymes and concentration of digestive juices in different regions.

It permits more time for enzymatic action.

Additional physical cutting and grinding of the food bolus is made possible.

All of the above are advantages

answer : All of the above are advantages

Explanation:

An animal with a gastrovascular cavity has some advantages over the animal with a tube-type digestive system . a gastrovascular cavity allows for the digestion and transport of nutrients across the body and is found in phyla and Platyhelminthes

The major advantages the gastrovascular cavity has includes :

It allows the animal to consume a second meal while the first is being digested.

It permits development of specialized enzymes and concentration of digestive juices in different regions.

It permits more time for enzymatic action.

Additional physical cutting and grinding of the food bolus is made possible.

lisov135 [29]
The Kuiper belt is home to three officially recognized dwarf planets: Pluto<span>, </span>Haumea<span>, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and </span>Saturn<span>'s Phoebe, are also thought to have originated in the region.

So the answer is Saturn

Thats what NASA will tell you, but they think the world is round so be careful when they give you "facts"</span>

How many chromosomes does a body cell for the organism (egg and sperm) have?
DiKsa [7]
Growth and repair
creation of gametes (sex cells)
method of reproduction in unicellular organisms
Binary Fission - type of reproduction that occurs in bacterial cells, single celled organism splits and becomes two identical organisms

Chromosomes and DNA

Chromosomes are DNA wrapped around proteins to form an X-shaped structure.



The diagram will help you see the relationship.

1. Chromosomes are found in the nucleus
2. Chromosomes are made of DNA
3. Sections of chromosomes are called genes



DNA - deoxyribonucleic acid (it is the genetic code that contains all the information needed to build and maintain an organism)





Chromosome Structure







Chromosome Numbers

Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell.

Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID.

Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID

Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes.

Diploid cells have 23 homologous pairs = total of 46

Haploid cells have 23 chromosomes (that are not paired) = total of 23

Homologous Chromosomes



Sex Determination

Chromosomes determine the sex of an offspring. In humans, a pair of chromosomes called SEX CHROMOSOMES determine the sex.

If you have XX sex chromosomes - you are female

If you have XY sex chromosomes - you are male

During fertilization, sperm cells will either contain an X or a Y chromosome (in addition to 22 other chromosomes - total of 23). If a sperm containing an X chromosome fertilizes an egg, the offspring will be female. If a sperm cell containing a Y chromosome fertilizes an egg, the offspring will be male.

Creation of a Zygote

When two sex cells, or gametes come together, the resulting fertilized egg is called a ZYGOTE

Zygotes are diploid and have the total 46 chromosomes (in humans)

Karyotype

A karyotype is a picture of a person's (or fetus) chromosomes. A karyotype is often done to determine if the offspring has the correct number of chromosomes. An incorrect number of chromosomes indicates that the child will have a condition, like Down Syndrome

Compare the Karyotypes below













Notice that a person with Down Syndrome has an extra chromosome #21. Instead of a pair, this person has 3 chromosomes - a condition called TRISOMY (tri = three)

Trisomy results when chromosomes fail to separate - NONDISJUNCTION - when sex cells are created. The resulting egg or sperm has 24 instead of the normal 23.

Other conditions result from having the wrong number of chromosomes:

Klinefelters Syndrome - XXY (sex chromosomes)

Edward Syndrome - Trisomy of chromosome #13
