One primer attaches to the __ end of the gene region on the 5' to 3' strand, another to the ___ end of the gene region of the 3' to 5' strand. This was maybe not explicit in the video. 3’ and 5’ refer to the orientation of the DNA strand. The 3’ end is the end that has the OH group used for adding new nucleotides. The 5’ end is the end where a phosphate sticks out from the ribose. The two strands that make up the DNA molecule run anti parallel to each other. Synthesis is always in the 5’ to 3’ direction (because that is where new nucleotides attach), and the template strand is read 3’ to 5’ (because it runs antiparallel).

D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds

Explanation:

Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question. This unique properties can be attributed to the HYDROGEN BONDING that holds the molecules of water together.

However, the hydrogen bonding of water molecules is an attractive force that is quite WEAKER than ionic or covalent bonds but it holds water molecules tightly to one another.

Answer:

By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different  materials and placed in the freezer

Explanation:

Experimental design

Materials given: freezer, a thermometer, samples of materials

setup:

1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.

2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.

3. after the time, the final temperature on the thermometer is recorded.

Result interpretation

The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat

independent variables: type of material used

dependent variables: temperature on the thermometer

control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.

Answer:

c or e

Explanation:

The correct answer would be the child's maternal grandmother or grandfather.

For X-linked traits, only females can be carriers while males are either affected or totally free from the trait. This is because females have two X (XX) chromosomes while males have only one (XY).

Since the couple is normal, it means the father is free from color blindness. The only available option now is the mother and since she is phenotypically normal, it means that she is a carrier of the disease. She must have inherited the allele from either of her parents, but not from both. If she had inherited an affected X chromosome from each of her parents, she would have been phenotypically affected for color blindness.

Hence, the child's color-blind allele can only be traced back to either of the child's maternal grandmother or grandfather.

The correct option is c or e.

The member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

In conclusion, the member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

Answer: 0.5. 1. 2. 3. 5

Explanation:

When the speed of the bottle is 2 m/s, the KE is These are the responses to the speed question: 0.5, 1.125, 2, 3.125 and, 4.5

Speed is defined as the distance that is allegedly covered in a given amount of time. It is regarded as the speed at which anything is said to move.

In this instance, speed is estimated as 1/2mv2.

As a result, the variables for calculation are:

If the bottle is moving at 2 m/s, then

= ½ (0.250) (2) ^2

= 0.5

If the bottle is moving at 3 m/s,

= ½ (0.250) (3) ^2

=1.125

If the bottle is moving at 4 m/s, then

= ½ (0.250) (4) ^2.

= 2

If the bottle is moving at 5 m/s, then

= ½ (0.250) (5) ^2

= 3.125

= ½ (0.250)(6)^2

=4.5

Therefore, It is regarded as the speed at which anything is said to move.

Explanation:

Answer:

temperature

Explanation:

The independent variable would be the colored water at different temperatures.

The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.

In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.

Answer:

The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.

Explanation:

The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.

Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).

The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.

The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.

The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.

Answer:

1. Effects of Acid Rain on Fish and Wildlife

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

2. Effects of Acid Rain on Plants and Trees

Dead or dying trees are a common sight in areas affected by acid rain. Acid rain leaches aluminum from the soil.  That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

3. Buffering Capacity

Many forests, streams, and lakes that experience acid rain don’t suffer effects because the soil in those areas can buffer the acid rain by neutralizing the acidity in the rainwater flowing through it. The soil becomes thin because of this and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.

4. Episodic Acidification

Melting snow and heavy rain downpours can result in what is known as episodic acidification. This can result in short-term stress on the ecosystem where a variety of organisms or species may be injured or killed.

5. Nitrogen Pollution

It’s not just the acidity of acid rain that can cause problems. Acid rain also contains nitrogen, and this can have an impact on some ecosystems. For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.

Explanation:

Not sure if this is what the question was asking for.

Acid rain is defined as rain or any other kind of precipitation that is particularly acidic, including high quantities of hydrogen ions. Acid rain has a pH lower than drinking water, ranging from 4-5 on average.

1. Acid Rain's Impact on Fish and Wildlife

Acid rain's biological consequences are most visible in aquatic areas such as streams, lakes, and marshes, where it can affect fish and other species. Acidic rain water can drain aluminum from soil clay particles as it passes through the soil and into streams and lakes.

2. Acid Rain's Effects on Plants and Trees

In acid rain-affected locations, dead or dying trees are prevalent. Aluminum is leached from the soil by acid rain. Aluminum may be damaging to both plants and animals. Acid rain also depletes the soil of minerals and nutrients required by trees to develop.

3. Capacity for Buffering

Many woods, streams, and lakes that experience acid rain remain unaffected because the soil in such locations can buffer the acidity in the precipitation flowing through it. As a result, the soil becomes thin and unable to effectively neutralize the acid in the rain water. As a result, these locations are more sensitive, and the acid and aluminum can build up in the soil, streams, and lakes.

4. Acidification on Occasional Basis

Melting snow and strong rain can cause a condition known as episodic acidification. This can cause short-term stress in the environment, injuring or killing a range of creatures or species.

5. Nitrogen Pollution

Not only may the acidity of acid rain cause difficulties. Acid rain includes nitrogen, which can have an influence on some ecosystems. Nitrogen contamination in our coastal waterways, for example, is partly to blame for dwindling fish and shellfish populations in some locations. Aside from agriculture and sewerage, much of the nitrogen created by human activities that reaches coastal waterways originates in the atmosphere.
