What is the counterstain in the Schaeffer-
Fulton endospore stain procedure?
Answer:
The Schaeffer–Fulton stain is a technique designed to isolate endospores by staining any present endospores green, and any other bacterial bodies red. The primary stain is malachite green, and the counterstain is safranin, which dyes any other bacterial bodies red.
As animals have progressed from sponges through mammals, describe in detail 2 ways animals have become more complex?
Answer:
1: Developed Digits
2: Developed senses
Explanation:
Optimal foraging theory suggests that:__________
a. when search time is long relative to handling time, predators should be generalists.
b. when handling time is long relative to search time, predators should be generalists.
c. new items are added to the diet only if their handling time is larger than average.
d. specialized diets are rare in nature.e.none of the above
Answer:
a. when search time is long relative to handling time, predators should be generalists.
Explanation:
In behavioral ecology, the optimal foraging theory can be used to predict animal behavior related to the search for food. Animals need to take different foraging approaches in order to obtain better energy cost benefits. This theory proposes that natural selection chose animals that maximize their adaptive fitness by adopting the better (economically effective) foraging pattern according to its environment. Moreover, animals are regarded as generalists when they are capable of surviving in many different habitat conditions and/or eat different types of foods (omnivores are generally generalist species). In this case, predators with large search times don't have time to choose between different prey, thereby they will be generalists.

a. Eric H. Davidson
b. Eric Carroll
c. Isabelle S. Peter
d. Jennifer Doudna
Answer:
a. Eric H. Davidson
Explanation:
Eric H. Davidson was a developmental biologist whose work helped to understand gene regulation networks in an evolutionary context, being a pioneer in understanding embryogenesis at the genome level. He especially studied sea urchin development, a model animal for developmental biology and genomics. He focused on the animal's nucleic acid properties through the process of hybridization (which has enabled us to understand molecular interactions during development as a whole system), shedding light on the molecular basis of sea urchin development. Eric H. Davidson also compiled the first list of 'fully sequenced' sea urchin genes, involving especially transcription factors, and their interactions with cis-regulatory sequences.
Answer:
a. Eric H. Davidson
Explanation:
Davidson, a developmental biologist, was a pioneer researcher and theorist of the gene regulatory networks that perform complex biological processes, such as the transformation of a single-celled egg into a complex organism. His work helped to reveal how the DNA sequences inherited in the genome are used to initiate and drive forward the sequence of steps that result in development.

To obtain energy from starch and glycogen, the body must begin by Group of answer choices converting both starch and glycogen to fatty acids. removing one glucose at a time with a condensation reaction. hydrolyzing both starch and glycogen to glucose. hydrolyzing the starch to glucose and the glycogen to amino acids.
Answer:
Hydrolyzing both starch and glycogen to glucose
Explanation:
Starch and glycogen are both forms of carbohydrates called "polysaccharide" found in the foods we consume. Polysaccharide are polymers that constitutes several monomeric units called monosaccharides. Monosaccharides are the forms in which the body can absorb energy.
Hence, starch and glycogen as polysaccharides must first be hydrolysed (broken down) into a monosaccharide called GLUCOSE in order to obtain energy for the body.
Which of the following observations can be explained by plate tectonics?
PLEASEEE HELPP
Continental crust is tertiary crust, formed at subduction zones through recycling of subducted secondary (oceanic) crust. The average age of the current Earth's continental crust has been estimated to be about 2.0 billion years. Most crustal rocks formed before 2.5 billion years ago are located in cratons.

The one that is explained by plate tectonics is shape and size of rock formation in caves. The correct option is C.
What is plate tectonics?Plate tectonics is the widely accepted scientific theory that the Earth's lithosphere is made up of a number of large tectonic plates that have been slowly moving since approximately 3.4 billion years ago.
Cooler parts of the Earth's crust were pulled downwards into the warmer upper mantle around 4 billion years ago, damaging and weakening the surrounding crust.
According to the authors, the process repeated itself until the weak areas formed plate boundaries.
A mass movement of the bedrock creates tectonic caves. The rocks separate along joints or fractures and are mechanically pulled apart.
The resulting cave is typically a high, narrow fissure with nearly planar walls and matching patterns on both sides of the passage.
Thus, the correct option is C.

What pattern of growth will a population with limited resources show?
Select one:
O a. density-independent
O b. logistic
O c. exponential
O d. density-dependent
Answer:
b. logistic
Explanation:
Logistic growth occurs when growth begins as exponential but then slows and flattens out (or becomes constant) at a certain point. The growth of a population is logistic because at the beginning all populations growths are exponential. This is because there are more than enough resources when a population is small. However, once a population reaches carrying capacity, which is the limit an environment can hold, resources begin to run out and the growth becomes slower and constant. Logistic growth is also known as an "S curve" because on a graph the growth resmbles an S.

Which system has atoms with the highest average kinetic energy?
room temperature
non of these
cold water
warm water
Answer:
warm water
Explanation:
Kinetic energy refers to the energy that possesses an object due to the motion of its molecules. Kinetic energy is positively associated with temperature. When heating water, water molecules gain kinetic energy and move faster than the molecules of cold water. In consequence, the temperature of an object can be considered as the average amount of kinetic energy that its molecules carry.

Explanation:
the fossils are the evidence of evolution
Answer:
Fossils
Explanation:
Fossils:fossils are the traces or impressions of dead plants and animals preserved in the rocks.The study of fossils is the strongedt evidence to support evolution.Nowadays,the age of fossils can also be determined accurately by using carbon dating process.Studying fossils have revealed the organisms in past is different from the present days.It also shows gradual process from simple to complex forms as time passes.Thus the study of fossils support the study of evolution.

How can a mutation result in a new trait (as seen with the Scottish Fold cats)?
Variations in an organism's genome that modify the activity of genes or the function of proteins can give rise to new characteristics in that organism.
What are scottish fold cats?Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.
A domestic cat breed known as the Scottish Fold has a naturally occurring dominant gene mutation that affects cartilage throughout the body and causes the ears to "fold," bending forward and downward toward the front of the head, giving the cat what is frequently referred to as an "owl-like" appearance.

The angle of Earth's tilt has changed throughout Earth's history and is still changing today. If Earth's tilt were to decrease
from 23.5° to 20.2°, which of the following changes do you expect would occur
Answer:
The world climate would drastically change.
Explanation:
First off, both poles would have rapid expansion, with the freezing of more water near the poles.Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.Deserts would expand and the average temperature would rise.Also, many animals would also die out, because of the change in their environments.Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.Answer:
Changes between seasons would be less drastic. (Is the right answer)
