MALE BONES ARE BIGGER AND STRONGER, in both size and density. Peak male bone mass is around 50% more than women’s, and women lose bone faster as we age. Black people have significantly stronger bones than whites: black women’s peak bone mass is the same as white men’s.

WOMEN AND MEN HAVE THE SAME NUMBER OF RIBS. We have 12 pairs, though some people are born with 11 or 13 pairs to no ill effect.

MEN HAVE BIGGER HEADS AND LONGER ARMS AND LEGS than women, relative to body size. Sources differ on comparative limb length but they all agree women have smaller, lighter heads & necks. Did you know a human head weighs about 5kg?

The biological sex of an adult skeleton can be determined with 95% accuracy by measuring the hip bones alone, 83% accuracy by the skull, and 80% accuracy by the long bones (femur & tibia).

WOMENS ELBOWS AND SHOULDERS are slightly different from men’s. Our arms bend a little further from our bodies and are more mobile at both joints.

FINGER LENGTH: Greater exposure to androgens in utero leads to a 4th (ring) finger that is longer than the 2nd (index), as often seen in men.

WOMEN HAVE A LONGER TORSO. Our skeleton accommodates extra reproductive organs and finds space to push things out of the way during pregnancy. It makes our legs shorter than men’s.

THE LARGER FEMALE PELVIS is better adapted for childbirth. It’s wider, longer, and held together by ligaments that soften during pregnancy, allowing the two halves to slide apart because of their narrow pelvis. Women’s slanted thigh bones put extra pressure on the knee joints, which have to rotate while men’s do not.

MEN HAVE BIGGER BRAINS by more than 10% relative to body size. Women’s brains have more connections between the two hemispheres, using both sides of the brain much more often than men.

Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short pl
zloy xaker [14]

Answer:

1. tall (or heterozygous)

2. 3:1

3. carriers

4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.

5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.

6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.

7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.

Which ecosystem(s) would have more biodiversity that farmland?
anzhelika [568]

Answer:

biodiversity

Explanation:

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Which phylum forms a connection between the chordates and the nonchordates? The phylum forms an evolutionary connection between
Mariulka [41]

Answer:

The phylum Hemichordata is the one that could form an evolutionary connection between the chordates and non-chordates.

Explanation:

To the phylum Hemichordata belongs a genus that scientists believe could explain how the chordates could evolve from the non-chordates. This genus is Balanoglossus, of the class Enteropneusta.

Balanoglossus is similar to a worm, whose habitat is the seabed, and like other hemicordates it has a stomach, a structure that forms part of its digestive system and fulfills the functions of a spine.
