If two substances are chemically combined and there is a release ofenergy, the reaction is described as
a. exothermic.
b. analytic.
c. endothermic.
d. catalytic.

Answers

Answer:

a. Exothermic.

Explanation:

We know that there are several types of chemical reactions. In some reactions, the energy which is absorbed to break down the bonds of the reactants becomes less than the energy which is released at the time of forming new bonds of the products.

This means that in the whole reaction, energy is released as either light or light. This type of reaction is called an exothermic reaction.

Why do erythrocytes swell and burst when placed in water? (A) Since water concentration is higher outside the cell, water moves inward by passive diffusion.
(B) Since hemoglobin concentration is higher inside the cell, hemoglobin moves outward by exocytosis.
(C) Since potassium ions are more concentrated inside the cells, potassium ions move outward by osmosis.
(D) Erythrocytes pump water inward by active transport to balance osmotic gradients.
(E) Water is a universal solvent and simply dissolves the erythrocyte membranes.

Answers

A.
There is more sodium inside the cell than outside. There is a saying that "water follows salt". It is found in the case of osmosis and the semipermeable membrane around the cell. In this case there is more salt inside so water will move inside. The cell can break with too much water.

Select all that apply.Which characteristics are common to both birds and reptiles?
scales
ectothermic
amniotic eggs
beaks
feathers
hollow bones

Answers

The answer is scales and amniotic eggs.

It is obvious that reptiles have scales, which are very important for their survival. But birds have scales, too. Their claws, feet, legs and beaks are covered by scales.
Reptiles and birds, together with mammals, belong to the group of Amniote, which means their eggs are amniotic. Amniotic eggs are either laid on land or retained inside the mother, unlike anamniotic eggs that are laid in the water.

Some of the listed characteristics are not common to both groups:
- Only reptiles are ectothermic (cold-blooded animals) while birds are endothermic (warm-blooded animals).
- Birds have beaks and reptiles have teeth.
- Birds are the only animals with feathers.
- Birds have hollow bones, and thus, lighter which help them to fly. Reptiles bones are dense and heavy.

Answer:

Scales

Amniotic eggs

Beaks

Explanation:

According to the reading,

"Birds are said to have evolved from the Reptilia. They do have some similar features. They have scales on their legs and feet; they lay amniotic eggs, but with a hard shell; they have beaks, similar to many reptiles, particularly turtles."

Positive feedback is most like _____.

Answers

Positive feedback is most like adding wood to a burning fire to increase the heat.

Positive feedback is a regenerative feedback process in which a segment of the output is combined with the input for the output to increase more. Components of a positive feedback loop include a stimulus or change, a sensor, a control center and an effector. Examples of positive feedback include the process of labor and childbirth and blood clotting.

Positive feedback is most like adding wood to a burning fire to increase the heat.

Which of the following senses is most closely related to balance? A. Touch
B. Smell
C. Hearing
D. Taste

Answers

C. Hearing

Ears are also responsible for balance, in the part of the Cochlea.

Here you will find a liquid-filled cavity that functions to maintain balance and movement.

Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.

These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.

in an investigation on accuracy and precision, myriah measures the mass of a 10.00 g piece of metal several times. her measurement are 9.98g, 10.02g, and 9.99 g.

Answers

None of Myriah’s measurements match the known value of 10 g, so her measurements are not accurate. Also, each of Myriah’s measurements come out different every time she measures, so her measurements aren’t precise either.
