Herd behavior in elephants ensures that individuals are protected and the species is perpetuated.

<h3>What is her behavior?</h3>

It is a behavior that is characteristic of animals that form herds.

Herds generally refer to groups of animals that live or move together or both.

By protecting individual elephants that are weak or young from being preyed upon by lions and leopards, more members of the population survive.

When more members of the population survive, the species is perpetuated and the likelihood of going into extinction reduces.

The reaction of hemoglobin with oxygen can be written as follows. hb + o2 â hbo2 if the amount of oxygen available to the blood
riadik2000 [5.3K]
Oxygen is needed to carry out a lot of biochemical processes in the body. If the amount of oxygen available to the blood decreases significantly a lot of things will go wrong in the body. For instance, lack of adequate oxygen will lead to the death of neurons which will eventually leads to brain cells death and irreparable brain damage. Oxygen is also needed for cellular respiration, without respiration, there will not be oxygen for carrying out various cellular activities and this will result into death. Oxygen deprivation will also leads to difficulty in breathing and other associated problems.

A boy weighing 25 kg sits in a 1000 kg car at a speed of 15 m/s. What is the total momentum of the car and the boy?
dexar [7]

Answer:

D) 15375kgm/s

Explanation:

weight of the boy 25kg +weight of the car 1000kg= 1025kg so momentum =mass × velocity. so it's SI unit is = kg×m/s = kg m/s.

1. Freon (CCl2F2) is commonly used in refrigerators and air conditioners as a coolant. How many grams of fluorine are there in t
Georgia [21]

Answer:

285g of fluorine

Explanation:

To solve this problem we need to find the mass of Freon in grams. Then, with its molar mass we can find moles of freon and, as 1 mole of Freon, CCl₂F₂, contains 2 moles of fluorine, we can find moles of fluorine and its mass:

<em>Mass Freon:</em>

<em>2.00lbs * (454g / 1lb) = </em>908g of Freon

<em>Moles freon -Molar mass: 120.91g/mol- and moles of fluorine:</em>

908g of Freon * (1mol / 120.91g) =

7.5 moles of freon * (2moles Fluorine / mole Freon): 15 moles of fluorine

<em>Mass fluorine -Atomic mass: 19g/mol-:</em>

15 moles F * (19g / mol) =

<h3>285g of fluorine</h3>

The reactant concentration in a first-order reaction was 7.60 x 10-2 M after 35.0 s and 5.50 x 10-3 M after 85.0 s. What is the
8090 [49]

Answer:

k = -0.0525 s⁻¹

Explanation:

The equaiton for a first order reaction is stated below:

ln[A]=−kt+ln[A]₀.

[A] = 5.50 x 10⁻³ M

[A]₀ = 7.60 x 10⁻² M

t = 85.0 - 35.0 = 50.0 s

The rate constant is represented by k and can be calculated substituting the values given above:

k = (ln[A]₀ - ln[A])/t

k = (ln5.50 x 10⁻³ M - ln7.60 x 10⁻² M)/50.0s

k = -0.0525 s⁻¹
