Explanation: Algae is at the bottom of the food chain, but provides all the energy for each organism in the ecosystem through photosynthesis
B. absorb bilirubin
C. synthesize vitamin K and B-complex vitamins
D. synthesize vitamins C and D
pair of numbers shows the chromosome number of
a normal gamete from each of these species?
The human gamete cells are expected to be 23 chromosomes in number while the gamete cells of a frog will contain 12 chromosomes.
A gamete cell refers to a reproductive cell in an organism. We must note that the chromosomes in gamete cells are haploid. This means that they only possess half of the normal number of chromosomes.
Now, for humans, the gamete cells will contain 23 chromosomes while the gamete cells of a frog will contain 12 chromosomes.

CAN YOU PLS MARK ME BRAINLEST THAMK YOU HAVE A NICE DAY!
We are given with 2 genes homozygous tall plants (TT) with homozygous short plants (tt). The ensuing offspring are tall, which implies the dominant attribute is tallness. this can be true since the chance of various height like all are short or some are tall and short could also be doable. answer is a
allele for tall plant height was dominant
Explanation:
Gregor Johann Mendel, called the "father of recent biology," was born in European country in 1822. His experiments showed that the inheritance of bound traits in pea plants follows explicit patterns, later turning into the inspiration of recent biology and resulting in the study of heredity.
A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.
Answer : According to the octet rule, sodium wants to lose an electron.
Explanation :
The given element is sodium with atomic number 11 that means it has 11 electrons.
The electronic configuration of sodium will be,
From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.
According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).
Hence, according to the octet rule, sodium wants to lose an electron.
