Answer: 1/2

Explanation:

Since it has a code "having freckles" is dominant (f) over the allele that codes for "no freckles".

The father is heterozygous

The mother is homozygous recessive

To understand the concept better:

Homogenous trait is made up of two same alleles whereas heterozygous traits are made up of two different alleles.

Example:

Homogenous allele: PP or pp

Heterozygous allele: Tt

To determine whether it is dominant or recessive:

The allele is said to be  dominant if it has Pp and recessive when the allele is pp

So the probability is 50% of having freckles and 50% of not having freckles

In the context of protein digestion, protein breakdown into its amino acid constituents is completed by?
Artemon [7]

In the context of protein digestion, protein breakdown into its amino acid constituents is completed by <u>proteases </u><u>produced in the small intestine</u>

<u />

  • Protein-degrading enzymes are referred to as proteases. These enzymes are produced by bacteria, fungus, plants, and mammals.
  • Proteins in the body or on the skin are broken down by proteolytic enzymes.
  • This may aid in digestion or the breakdown of proteins that contribute to inflammation and pain.
  • The small intestine, pancreas, and stomach all manufacture protease.
  • The stomach and small intestine are where the majority of chemical reactions take place.
  • Pepsin is the primary digestive enzyme that targets proteins in the stomach.
  • Proteases are released by the pancreas into the proximal small intestine, where they combine with proteins that have already been altered by gastric secretions and break them down into amino acids, which are then absorbed and utilized by the body as necessary.

Meat is not a good source of protein because it does not provide the body with all the essential amino acids.
tankabanditka [31]

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

Compare what ways are planets and<br> dwarf planets similar.
Cerrena [4.2K]
So the similarity of the planets and the dwarf planets are they are both mostly round because they have sufficient gravity to flatten their own surfaces into a sphere. The differences are that planets are big enough to clear the whole region of space where they orbit the sun whereas dwarf planets do not.

How many organelles are in plant cells? please list them. :)
Murrr4er [49]
There are 11 organelles in total, 
vacuoles: they store water
Chloroplasts: trap energy from the sun to produce food for plant cell
Cell wall: provides support and protection to the cell membrane, 
Cell membrane: thin flexible barrier around a cell, controls what enters/ leaves the cell
Nucleus: 'The control center', carries the DNA of the cell
Ribosomes: Found in all cells, their jobs are to make protein 
Endoplasmic Reticulum: The internal delivery system of the cell
Golgi complex: Transports materials throughout the cell
Lysosomes: Break down food into particles the cell can use. another function is they destroy old or dying cells 
Mitochondria: Breaks down food to make ATP 
and last but not least cytoplasm a jelly like fluid in the cell that keeps the organelles suspended
