1) $\text{ Turtles and leopards all have four limbs and an amnion. }$ True

2) $\text{The common ancestor of lamprey and lancelets had a vertebral column. }$ False

This is because their ancestor is a Chordate who doesn't have a vertebral column but a notochord.

3) True

$\text{Frogs are the sister taxa of turtles and leopards because they are more }$

$\text{related to a common ancestor.}$

4) $\text{Leopards and bass are more closely related than turtles and bass}$ False

This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).

5) $\text{The taxon that shares the most recent common ancestor with frogs is the bass.}$ False

The taxa of turtles share a more common ancestor with frogs compared to bass.

6) $\text{Leopards and lancelets have no common ancestor. }$ False

2.265 kg is the weight for a small bag of sugar. You are baking cupcakes for a school fund drive. It takes 100 g of sugar to mak

katovenus [111]

The total batches of cupcakes that you make with one small bag of sugar will be 22 batches

From the question, we are given the following

Weight of a small bag of sugar = 2.265kg = 2265grams

Since 100g of sugar to make one batch of cupcakes, then:

100g = 1 batch ... 1

In order to get the number of batches of cupcakes can you make with one small bag of sugar, we can write:

2265g = x ... 2

Divide both expressions;

100/2265 = 1/x

100x = 2265

x = 2265/100

x = 22.65 batches

Hence the batches of cupcakes that you make with one small bag of sugar will be 22 batches

An experiment to measure the rate of respiration in crickets and mice at 10 degrees Celsius and 25 degrees Celsius was performed

larisa [96]

Answer:

A substance that removes carbon dioxide gas

Explanation:

Options-

A. A substance that removes carbon dioxide gas

B. A plant to produce oxygen

C. A glucose reserve

D. A valve to release excess water

Solution -

It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.

Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption

Option A is correct
