Answer:
option (a) because....,
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). ... Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA)
option (b) not because,
Within that centrosome there are two centrioles. And centrioles are physical objects made up of things called microtubules.
option (c) not because....,
Centromere repeats in humans are made up of alpha-satellite DNA, a ∼171 bp sequence or monomer that is iteratively repeated. Alpha-satellite monomers are arranged head-to-tail and organized into repeated arrays called higher order repeats (HORs) that range from 0.2 to 5 megabases (Mb) and are chromosome specific.
not option (d) because...,

Answer:
Dampak negatif manusia terhadap lingkungan adalah:
Kelebihan penduduk, polusi, pembakaran bahan bakar fosil, dan penggundulan hutan. Perubahan seperti ini telah memicu perubahan iklim, erosi tanah, kualitas udara yang buruk, dan air yang tidak dapat diminum.
Dampak positif manusia terhadap lingkungan adalah:
Melindungi spesies yang terancam punah dan membersihkan danau dan laut memiliki efek positif terhadap lingkungan. Di rumah, Anda dapat membantu planet ini dengan mendaur ulang limbah dan menanam tanaman atau sayuran.
Answer:
3/4
Explanation:
If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.
<h3><u>Gene A</u></h3>
AA x Aa
- F1 genotypes: 1/2 AA, 1/2 Aa
- F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>
BB x bb
- F1 genotypes: 1 Bb
- F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>
Cc x Cc
- F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
- F1 phenotypes: 3/4 C, 1/4 cc
We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>
