Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.

In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.

Georgia [21]

Answer:

The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...

The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.

Explanation:

From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...

The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.

The minerals and vitamins present are in a way they can be absorbed.

Why is it wrong to say that bread is a compound?
tatiyna

Explanation:

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

Bread is a mixture of several compounds such as sugars, proteins, lipids and gases along with a culture of organisms or chemical leavEning agaent. Several of these components

Explanation:

Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).

  • Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.                                                                 Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding
  • Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.                Basic makeup: C, H, O -with many polar OH groups
  • Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers. The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties.                                                                     Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids.

An octopus reproduces only once in its life, but it may have more than 100,000 offspring, depending on the species. Certain spec
galina1969 [7]

Answer:

<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>

Explanation:

Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.

On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
