Answer:

Answer:

These seed plants fall into two groups, angiosperms and gymnosperms. Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary, which usually ripens into a protective FRUIT.

Hey there! Now that I know its for your science project , Id be more than  happy to help ( if this was from your text book, It might have not been right since some text books might not mention the method I would have given you)

Sooo.. Here we go.. For my science project This is the method I used...

step 1 ) Go to your fridge 
step 2) Go grab a piece or two of white or wheat toast. Its preferable to use both so you can see and compare the difference.
step 3) (before you do anything else, since it is a science project, your teacher might want a hypothesis, with observations and data, and a conclusion to your experiment, so just make sure you have those done if you have to.)
Step 4) go get 2 Ziplock bags, preferably the one that you zip and seal..
Step 5) Place the wheat toast in one bag, and place the other toast in the other bag...
Step 6) Make sure that when you put the toast in the bags , you take all the air out of the bag, make sure there is no air at all!
Step 7) put the toasts in a dark place with no light and very little air. The place I put them was the closet that I never opened. 
Step 8) Leave them there for about 7-9 days 
Step 9) Take it out... 
The results are going to be gross... you should see weird fuzzy things (mold,fungus, bacteria, etc.)
Thats when your project is complete..

PLEASE DO NOT TOUCH OR EAT THE TOAST.. WHERE PLASTIC GLOVES WHILE HANDLING THE TOAST, BECAUSE IT CAN GET YOU SERIOUSLY SICK!!!! DISPOSE OF IT AFTER YOU ARE DONE! THANK YOU!

Martina does not think cross species breeding should be allowed. Which of the following facts best supports her opinion? A) Mules are stronger and have more endurance than horses.
B) Genetically engineered proteins can help fight disease.
C)Quarter horses bred to compete in rodeos are fast and strong.
D) Mules cannot reproduce because they have an odd number of chromosomes.

Answers

Answer:

(D). Mules cannot reproduce because they have an odd number of chromosomes.

Explanation:

Cross species breeding may be defined as the process of breeding between two different species. For example, Mule is obtained by the breeding between male donkey and female horse.

Mules have odd  number of chromosomes and they are sterile. This is because, odd number of chromosomes leads to non-disjunction and formation of abnormal chromosomal separation during gamete formation. Due to this, non-functional gametes are formed during meiosis and mules cannot reproduce.

Thus, the correct answer is option (D).

Which of the following is not an organelle found ONLY in plant cells?

Answers

-Chloroplasts: Chloroplasts are the plant cell's "energy power plant" as well as mitochondria- they are involved in photosynthesis, making food and energy for the cell.

-Cell walls: Cell walls are rigid layers around the cell membrane. They are made of cellulose and help maintain the cell's shape and prevent it from swelling too much.

One organelle only in animal cells:

-Centrioles: Centrioles are structures that make spindle fibers for the movement of chromosomes in mitosis.

A different organelle:

-Vacuoles:

In plant cells, the vacuole is called a "central vacuole". The central vacuole is a large "balloon" that holds water, nutrients, ions, trash, etc. for the cell.

In animal cells, there are numerous smaller vacuoles. They have the same function.
The cell wall is only located in the plant cell

Which of these organisms are vertebrates in Kingdom Animalia?Choose all answers that are correct?

A.
worms

B.
frogs

C.
clams

D.
fish

Answers

Any of a subphylum (Vertebrata) of chordates consisting of animals (such as mammals, birds, reptiles, amphibians, and fishes) with a bony or cartilaginous spinal column that replaces the notochord.

The vertebrates are frogs and fish.

What are the characteristics of vertebrates?

  • The anatomy of vertebrates is strikingly similar, with the presence of a vertebral column, gastrointestinal tract, and spinal cord.
  • The notochord develops into a vertebral column, with the vertebrae on the dorsal side.
  • The presence of the central nervous system is an important indicator. The spinal cord's anterior nerve tube expands into the brain.
  • Jaws can be found in some vertebrates. Jawless species are included in the order of vertebrates.
  • The internal skeleton facilitates the distribution of various muscle attachment nodes.

Why frogs and fishes are vertebrates?

  • Frogs and fish are both members of the phylum Chordata and the subphylum Vertebrata.
  • Frogs and fish, like humans, have a spinalcord and a backbone.
  • Furthermore, all chordates have bilateralsymmetry.

Thus, we can conclude that Options B and D are correct.
