The correct answer is: cleavage.

Cleavage is one of the types of mineral breakage. It is the tendency of a to break along smooth planes which are parallel to zones of weak bonding. Cleavage can be cubic when the break occur in three directions at right angles or it can be rhombohedral when the break occurs in three directions that are not at right angles. There is also one and two-direction cleavage.

help I can't think of any for this question "State 5 different ways animals and plants interact in an ecosystem."

Oksana_A [137]

Answer:

Plants and animals benefit each other as members of food chains and ecosystems. For instance, flowering plants rely on bees and hummingbirds to pollinate them, while animals eat plants and sometimes make homes in them. When animals die and decompose, they enrich the soil with nitrates that stimulate plant growth. I know it's not 5, but I hope it helped.

In humans, syndactyly (webbed digits) is inherited by possession of a dominant allele (S). If a man who is homozygous and normal

____ [38]

Answer:

The % of children with webbed digits is $50$ %

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is $50$ %
