A shadow is caused when an object blocks sunlight. For example, when your body blocks sunlight, you may see a shadow of yourself

on the ground. How do you think the shadow of an object, such as a flagpole, would change over the course of the day as the Sun appears to move across the sky?

Answer:

The position of the sun affects the change in the direction and size of the shadow of the object. When sunlight is blocked by and object a shadow forms, as the earth moves on its axis daily it looks like the sun rises in the east and sets on the west.

When the sun is low in the sky the more light is blocked by an object which means the shadow will be longer and shadow will always point far from the direction of the sun.

In the morning sun is in the east so the shadow will be towards the west in the morning, shadows are long and point northwest and at noon, shadows are short and point north late afternoon shadows are long and towards the northeast.

Check all of the statements that are true regarding keratinized stratified squamous epithelium.
strojnjashka [21]

Answer;

-Keratinized stratified squamous epithelium forms the epidermis of the skin.

-In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

Explanation;

-Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. Stratified squamous epithelium may be keratinized or nonkeratinized. Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out.

-The cells on the surface of stratified squamous keratinized epithelium are very flat. Not only are they flat, but they are no longer alive. They have no nucleus or organelles. They are filled with a protein called keratin, which is what makes our skin waterproof.

ompared to eukaryotes, prokaryotes are ________. Compared to eukaryotes, prokaryotes are ________. simpler morphologically and m
Savatey [412]

Answer:

In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.

Explanation:

Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.

They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.

prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.

The cytoplasm is enclosed by cell membrane.

Molecular studies have reveal that eukaryotes are evolved from prokaryotes.

Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.

What term is specific to reactions in which simple compounds are combined into more complex molecules?
iris [78.8K]
Anabolic is a chemical reaction that fuses molecules in the body, the process is called anabolism.  It is gathering of normally manufactured hormones that are subordinates of testosterone, are utilized therapeutically particularly to advance tissue development, and are once in a while manhandled by competitors to build the size and quality of their muscles and enhance continuance.

Your assignment in biology lab is to design an experiment that would detect whether a substance is breaking down, or digesting,
Elis [28]

Answer: Option B

Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.

Option B is correct because it has all three criteria-                                                                                   1. Control [water + protein]                                                                                                               2. With enzyme [egg white + pepsin]                                                                                           3. With acid and enzyme

So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.

Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.
