Mendel found that the allele for tallness in plants (T) is dominant to the allele for shortness (t). What would possible results be if a heterozygous plant self-fertilizes?
_____ x _____
genotypic ratio: ____ : ____ : ____
phenotypic ratio: ____ : ____
What is the probability of having a homozygous tall plant? _____
When a plant self-fertilizes, is there still genetic variation between offspring and parent? ________
If a heterozygous plant self-fertilizes, the possible results are that the offspring will be either homozygous dominant (TT), heterozygous (Tt), or homozygous recessive (tt).
The genotypic ratio for the offspring of a heterozygous plant that self-fertilizes is 1:2:1, meaning that there is a 1 in 4 (25%) chance that the offspring will be homozygous dominant (TT), a 2 in 4 (50%) chance that the offspring will be heterozygous (Tt), and a 1 in 4 (25%) chance that the offspring will be homozygous recessive (tt).
The phenotypic ratio for the offspring of a heterozygous plant that self-fertilizes is 3:1, meaning that there is a 3 in 4 (75%) chance that the offspring will have the dominant trait (tallness) and a 1 in 4 (25%) chance that the offspring will have the recessive trait (shortness).
The probability of having a homozygous tall plant is 1 in 4 (25%) if a heterozygous plant self-fertilizes.
Even when a plant self-fertilizes, there is still genetic variation between the offspring and the parent. This is because self-fertilization only involves the mixing of the genes that are present in the parent plant, and it does not create new genetic variation. Therefore, the offspring of a plant that self-fertilizes will have the same genetic variation as the parent plant, but the specific combination of genes in each individual offspring may be different from the parent.

Answer:Agriculture is an important sector of the U.S. economy. The crops, livestock, and seafood produced in the United States contribute more than $300 billion to the economy each year.[1] When food-service and other agriculture-related industries are included, the agricultural and food sectors contribute more than $750 billion to the gross
Agriculture and fisheries are highly dependent on the climate. Increases in temperature and carbon dioxide (CO2) can increase some crop yields in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety.[3] Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt ecosystems. Overall, climate change could make it more difficult to grow crops, raise animals, and catch fish in the same ways and same places as we have done in the past. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices

of greenhouse gases decrease?
a. when sources equal sinks
b. when sources are less than sinks
c. when sources are greater than sinks
d. when anthropogenic sources are greater than
natural sources
e. when anthropogenic sinks are less than
anthropogenic sources
Answer:
a. when sources equal sinks
Explanation:
The difference between sources (emissions to the atmosphere) and sinks determines the change in a gas's concentration in the atmosphere (removals from the atmosphere). Many natural processes remove GHGs (“balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases”) from the atmosphere. In the ocean, carbon dioxide (CO2) dissolves and is absorbed by plants during photosynthesis. In the atmosphere, photochemical processes are principally responsible for the destruction of methane (CH4) and nitrous oxide (N2O).
In addition to naturally occurring biological activities like breathing, human activity also produces these gases. Only when sources and sinks are equal are GHG concentrations stable.

What do we call
variation that can
be inherited?
heritable variation this is answer
asexual reproduction
Answer: What do we call variation that can be inherited?
heritable variation
Explanation:
The term for variation that can be inherited is "heritable variation." It refers to traits or characteristics that are passed down from parents to offspring through genes. These traits can include physical features like eye color or height, as well as certain behaviors or abilities.
An example of heritable variation is hair color. If both parents have brown hair, there is a high chance that their children will also have brown hair. However, if one parent has blonde hair and the other has brown hair, there is a possibility that their children could have either hair color, depending on the specific genes they inherit.
The continents of South America and Africa, where Mesosaurus fossils are located, are currently about 4,000 km apart and separated by the Atlantic Ocean. GPS measurements show that the South American Plate and African Plate are currently spreading apart from each other at a rate of 3.0 cm per year.
Mesosaurus would have been unable to swim across the continents due to physiological constraints. This shows that during the Early Permian, South America and Africa were linked.
This divergent plate motion explains why Mesosaurus fossil bones previously discovered together are now located on continents thousands of kilometers apart.
What is the Early Permian?The Permian is a geologic epoch and stratigraphic sequence that lasted 47 million years, beginning with the end of the Carboniferous Period 298.9 million years ago and ending with the beginning of the Triassic Period 251.9 million years ago.

the least abundant cells of the epidermis are . keratinocytes intraepidermal macrophages melanocytes type i cutaneous mechanoreceptors tactile epithelial cells
The least abundant cells of the epidermis are type I cutaneous mechanoreceptors.
The epidermis is the outermost layer of the skin and is made up of several types of cells, including keratinocytes, intraepidermal macrophages, melanocytes, and type I cutaneous mechanoreceptors. Among these cells, type I cutaneous mechanoreceptors are the least abundant.
Type I cutaneous mechanoreceptors are sensory cells that are responsible for detecting light touch and pressure. They are found in the epidermis and are important for sensing texture, shape, and movement. Despite their importance for touch sensation, type I cutaneous mechanoreceptors are relatively rare in the epidermis and make up a small proportion of the cells in this layer.
Keratinocytes, intraepidermal macrophages, and melanocytes are more abundant in the epidermis compared to type I cutaneous mechanoreceptors. Keratinocytes are cells that produce keratin, a protein that helps to protect and strengthen the skin. Intraepidermal macrophages are immune cells that help to protect the skin from infection and inflammation. Melanocytes are cells that produce melanin, a pigment that gives color to the skin, hair, and eyes.
