Which level of organization is represented by the skeleton of the snake?
А.organ
B.organism
C.tissue system
D.organ system
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.

A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F1 offspring are yellow. What question can be answered with the F2 cross?
Answer:
See the answer below
Explanation:
The question that can be answered with the F2 cross would be if the yellow flower color is dominant over the red flower color in the species. In other words, whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.
Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to 3:1. Otherwise, a more complex pattern of inheritance would be involved.

Which is an appropriate conclusion for the data shown?
The decrease in carbon dioxide (CO2) for the leaf was less than the decrease for the stem.
- More oxygen was produced in the stem than in the leaf.
-There was no photosynthesis taking place in the roots.
- The stem was performing photosynthesis at a faster rate than the leaf.
Answer: I think Its the stem was performing photosynthesis at a faster rate than the leaf. But I'm not 100% sure, but I think its that one. I hope this helped!

What is the formula for speed of a wave?
Answer:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known
Explanation:
looked it up
Answer:
v = f λ
v is wave speed
f is frequency of the wave
λ is wavelength

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.
