a) Both animals have tails as embryos
b) Both animals have similar upper limb buds as embryos
c) Both animals have feathers as embryos
d) Both animals have structures similar to gill arches as embryos
e) Both animals use their upper limbs for the same function
Answers
Both chicken and the cat begin with a tail, though eventually for the chick, it looses its long tail. Unlike the cat it keeps the tail it had when it was a fetus. That’s a shared characteristic embryo until they are fully developed.

if a gene is made up of 20% adenine, how much thymine, guanine, and cytosine will there be
Answers
Explanation:
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

why do orangutans need so much space?
Answers
Answer:
Orangutans are the heaviest tree-dwelling animal
They spend most of their lives swinging through the canopies and need vast stretches of forest to find enough food and mates. Deforestation and hunting are the biggest threats to orangutans.orangutans need so much space because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas.Orangutans have large home ranges, which may overlap. Each adult female usually lives in a stable home range of about 3.5 square miles (9 square kilometers). An adult male's territory may be up to 15 square miles (39 square kilometers).

Answers
Answer:
ewan the anther to stigma pero dapat stamen to the stigma
Answer:
I believe the answer is "from an anther to the stigma"
Explanation:
Because to be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Select all the advantages of a multienzyme complex over a metabolic pathway
A. There is less room for substrates to diffuse away
B. Each enzyme can be activated or inhibited individually
C. The product of one enzyme will serve as the reactant for the next
D. The complex can be regulated as a group
Answers
Answer:
Option A, B, C
Explanation:
The major advantages of multienzyme complex over a metabolic pathway is that it do not require individual pathway for each enzyme activation or inhibition. Instead it responds efficiently to the equilibrium changes of substrate supply and demand as compared to that of enzymes.
It tightly regulates the processes and is also faster than that of the metabolic pathway.
Hence, option A, B and C are correct

Breathing heavily after running a race is your body's way of *
a. restarting glycolysis.
b. recharging the electron transport chain.
c. repaying an oxygen debt.
d. making more citric acid.
Answers
Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.

Salmon live in both fresh water and salt water during their lives. They are born in in fresh water but migrate out to marine waters for most of their life. Eventually, they return to the place they were born in fresh water to spawn. Changing between fresh water and salt water affects the balance of water in their body. Salmon have an internal control system called osmoregulation that restores the balance by negative feedback. This is an example of which characteristic of life
Answers
Answer: The question is incomplete because the options are not given. Here are the options gotten from another website.
A. adaptation
B. reproduction and development
C. response to the environment D. energy transformation
E. maintaining homeostasis
The correct option is maintain homeostasis which is C.
Explanation:
This is because salmon posseses adaptive physical characteristics that help it to suitably live both in freshwater and salt water. This is because homeostasis is the ability to resist any change in order to maintain body internal environment and this is a negative loop feedback. Organs of salmon work to control homeostasis but endocrine and nervous system engage more in maintain homeostasis.
The last option is correct.

it.
What is Trophic level?This is the position an organism occupies in a food chain. The organisms
are usually fewer while those at the bottom have more organisms present
in the chain.

Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)

Answers
Answer:
The correct answer is: -31 mV
Explanation:
Given:
Intracellular fluid concentration = 10 mM
Exracellular fluid concentration = 1 mM
temperature = 237+37 = 310 k
Z = 2
F= 96500 C mol-^1
R = 8.314 J MOL-^1K-^1
Formula -
Ex = (RT/ZF) ln ([x]out/[x]in)
= [tex]\frac{8.314*310*2.303}{2*96500} log 10 \frac{1mM}{10mM}[/tex]
= -0.03075447679*1/10 log 10
