Answer:
3/64 B- vv dd
Explanation:
We know that the alleles for all of the three traits assort independently. So we can think about them separately.
Coat color:
Let us say that the dominant allele coding for Black is B while the recessive allele coding for chocolate is b.
Parentals) Bb x Bb
F1) 1/4 BB, 2/4 Bb, 1/4 bb
Vision:
Let us say that the dominant allele coding for normal vision is N while the recessive allele coding for PRA is n.
Parentals) Nn x Nn
F1) 1/4 NN, 2/4 Nn, 1/4 nn
Hip joint
Let us say that the dominant allele coding for the normal hip joint is D while the recessive allele coding for dysplasia is d.
Parentals) Dd x Dd
F1) 1/4 DD, 2/4 Dd, 1/4 dd
Now, we need to know the chance that the first pup born to these dogs will be black, have PRA, and have hip dysplasia. The genotype of this individual would be B- nn dd, where the symbol - represents the dominant and/or the recessive allele.
Black coat = 1/4 BB + 2/4 Bb = 3/4 B-
PRA = 1/4 nn
Dysplasia = 1/4 dd
The probability of getting the first individual with these genotypes results from their multiplication.
3/4 B- x 1/4 vv x 1/4 dd = 3/64 B- vv dd
The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time. It is about a joint probability of two or more events that might happen simultaneously, not excluding each other. This rule is based on the dependence or independence of the events. Two events A and B are independent of each other if one of them does not affect the occurrence of the other one. For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is
P(A∩B) = P(A) x P(B)

Match each conservation effort with the resource it could directly help save.
saving forests
conserving freshwater aquifers
reducing CO2 emissions that contribute to climate change
Walk or use a bicycle for short-distance
travel.
Use computers for communication and
taking notes.
Treat sewage water and use it in factories.
Answer:
walk or bike reduces CO2
using computers helps save forests
treating sewage water conserves freshwater aquifers
Explanation:
walking reduces CO2 by not using a car train or bus that puts out CO2
computers for note taking saves forests by reducing the amount of paper we use, therefore cutting down less trees to make the paper
treating sewage water and reusing it in factories conserves freshwater aquifers because we're recycling used water rather than continuing to use more and more freshwater.
Answer:
Walk or use a bicycle for short-distance travel ; reducing CO^2 emissions that contribute to climate change
Use computers for communication and taking notes ; saving forests
Treat sewage water and use it in factories ; conserving freshwater aquifers
Explanation:

Which of the following best describes the importance of the phase of mitosis shown in cell 1?
In the given shown cell 1 , chromatids separate so that daughter cells have genetic information that is DNA similar to that of parent.
What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

Which statement is true about the oxygen content of wetlands? A. Most of the oxygen in wetlands comes from bacteria. B. Wetlands have the highest oxygen content of all freshwater biomes. C. Wetlands have lower oxygen levels than rivers or lakes. D. Water in wetlands contains zero dissolved oxygen.
Answer:
C. Wetlands have lower oxygen levels than rivers or lakes
Explanation:
Wetlands are also known as coastal regions. It is characterized by a vegetation that is flooded by water for most part of the year, if not all. Since water content of the soil is high, the oxygen content is very low.
Wetlands include marshes, swamps etc. and can harbor plant species adapted to the anoxic (lack of sufficient oxygen) state. Based on this, wetlands are said to have a lower oxygen levels than rivers or lakes.
Answer:Wetlands have lower oxygen levels than rivers or lakes.

What would happen to a backyard if it was left unattended for years?
Answer:
It's not so much what happens to the backyard, it would be overgrown with grass and weeds and probably be a new home to animals like snakes, but its more what would happen to what's in the backyard, tools and bikes would rust, soon anything indicative of a previous owner would hardly be recognizable
Explanation:
If the backyard of a garden is left unattended for years then the grass in that area will over-grow and a number of different organisms will inhabit in the area. The biodiversity of the area increase as well as rusting is observed.
What is Rusting?Rusting is the corrosion of iron. Rustin happens when iron is left open in air. The iron metal reacts with the oxygen gas in the humid condition which results into rusting of iron. The vehicles parked in the backyard will rust in this condition.
The biodiversity is the sum total of all the living organisms present in a particular area. When the backyard of a house is left unattended the grass in that area will grow very fast and this will cause the insects to inhabit in that area which will cause increase in the biodiversity.

When someone says the word "desert," what plant do you picture? You're probably
picturing the saguaro cactus. Saguaros are known for their long, tall branches that look like
arms. These branches don't start to grow until the cactus is 50 to 70 years old. The folds
along the saguaro's stem and branches are called pleats. What are they for? These pleats
store water for the cactus, which is important in the hot, dry desert. A desert plant's spikes
aren't just to keep animals away. They also help provide shade during the long hours they
spend in the sun.

Electronegativity can be used to predict the character of a bond between two elements. If the difference between the electronegativity of two atoms is greater than 2.0, which type of bond will be formed?
An isotopic bond
A polar covalent bond
A nonpolar covalent bond
An ionic bond
Answer:
The difference in the electronegativity of two atoms determines their bond type. If the electronegativity difference is more than 1.7, the bond will have an ionic character. If the electronegativity difference is between 0.4 and 1.7, the bond will have a polar covalent character.

What types of energy occurs when a grapefruit falls from a tree? TRUE OF FALSE: Combustion reactions occur in the presence of oxygen gas. * Energy is the ability to do work. * A renewable energy source is one that is replaceable. * Light energy is emitted by certain organisms such as fireflies and glow-worms. Sound energy cannot travel through air Heat energy cannot travel through a liquid for example water.
Answer:
The energy conversions that occur when a grapefruit falls from a tree is;
Potential energy ---> kinetic energy ---> potential energy
Combustion reactions occur in the presence of oxygen gas- True
Energy is the ability to do work - True
A renewable energy source is one that is replaceable - True
Light energy is emitted by certain organisms such as fireflies and glow-worms - True
Sound energy cannot travel through air - False
Heat energy cannot travel through a liquid for example water - False
Explanation:
According to the first law of thermodynamics, energy can not be created nor destroyed but is converted from one form to another. When a grapefruit falls from a tree, the energy conversion is as follows;
Potential energy ---> kinetic energy ---> potential energy
Combustion reaction refers to a reaction where a substance is burnt in oxygen to produce heat and light.
Energy is defined in science as the ability to do work. Renewable energy can be replaced. A typical example is solar energy.
Light energy is emitted by certain organisms such as fireflies and glow-worms.
Sound is a mechanical wave hence it must be transmitted through a medium. The medium through which sound waves are transmitted is air.
Heat travels through any thermal conductor. Water is an example of a good thermal conductor. Heat indeed travels through different liquids.
