G=Green....because your starting plant is heterozygous it must be Gg
g = yellow ....because yellow is recessive, it must be gg
Gg x gg
Do a Punnet Square and you get
Gg (2)
gg (2)
So half of your plants will be green (but heterozygous) and half will be yellow (homozygous)
Answer:
Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians
Explanation:
Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.
Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADT). When the ATP converts to ADP, the ATP is said to be spent.
Nerve cells from the retina to the back of occipital lobe are known as visual neurons which constitute the optic tract.
- The specialized neurons in the retina of the eye called rods and cones which are involved in perceiving light and creating images. They are known as photoreceptors.
- After taking in the light, these rods and cones transmit impulses to the optic nerve. T
- Optic nerve is a bundle of nerve fibers coming out of the eyeball from a point called blind spot where the rods and cones are absent and no image can be formed.
- The two optic nerves, one from each eyeball cross at the optic chiasm from where onwards they are known as optic tracts.
- The optic tract sends impulses from the optic chiasma to the visual cortex in the occipital lobe of the brain, which is where the image is experienced through visual neurons.
Hence, the correct answer is that they are called visual neurons which constitute the formation of the optic nerves and optic tract.
