Dogs with N/N (i.e, N = no curl) genotype are observed to have a straight hair coat. This curl variant cannot be transmitted to their offspring.
How are dogs' straight hair strands created?Dogs who have straight hair have two copies of the straight version of the gene (cc); dogs who have wavy hair have one copy of the straight form of the gene and one copy of the curly form (Cc); and dogs who have curly hair are homozygous for the curly mutation (CC).
The RSPO2 gene (furniture), FGF5 gene (long hair), and KRT71 gene (coat type) are the three genes involved (curly gene). Both the furnishings gene and the curly gene are dominant, and only one copy is necessary to have a coat that is furnished or curly, respectively.

For organotrophic and lithotrophic microbes, the two sources of electrons available for organisms are reduced organic compounds and ____
For organotrophic and lithotrophic microbes the two sources of electrons available for organisms are reduced organic compounds and reduced inorganic compounds.
Chemolithotrophs use various inorganic compounds as electron donors. The most common ones are hydrogen gas, sulfur compounds nitrogen compounds, and ferrous iron. It produces energy-reduced electron carriers and precursor molecules for cellular metabolism.
The most common terminal electron acceptors used during anaerobic respiration are nitrate and carbon dioxide, but metals and some organic molecules are also reduced. In anaerobic environments sulfates act as terminal electron acceptors and are reduced to sulfides leading to both the formation of metal sulfides in sediments and the evolution of hydrogen sulfide gas.

Mark for review (Will be highlighted on the review page)
The Ecological Footprint measures the rate at which nature can absorb our waste and supply resources in comparison to the rate at which humans use up resources and produce waste.
What does the term "ecological footprint" represent in environmental science?
Simply explained, ecological footprint is a byproduct of human activity and is based on the quantity of biologically productive land and water required to produce the goods we use and to consume the waste we produce.
How important is the environment's role on achieving sustainable development?
An ecological footprint concept can be used as a sustainable development indicator to show how people or businesses are working to reduce their negative environmental consequences.

Africa has been home to early anthropoid primates since the Eocene Epoch.
The earliest anthropoid apes appeared as least in the late Eocene. There is disagreement over the anthropoids' ancestry, or the progenitor of monkeys and apes.
The majority of the early fossil material, which dates to the Eocene Epoch (about 56-34 mya), is discovered in North America and Europe, even though primates are assumed to have developed in Asia.
Eosimiids may also be known from the early Eocene of India, although middle Eocene deposits in China and Southeast Asia provide the greatest support for stem anthropoid origins. By the late Eocene, crown anthropoid skeletons were undoubtedly found in Africa.

Blue poppies native to China were grown at a plant-breeding center in California. The plants with the thickest leaves were most likely to survive and reproduce in the drier climate. After several generations, the percentage of thick-leaved plants had increased by 42%. This adaptation of the poppies to their new environment is due to _____.
- directional selection
The characteristics of the poppies shifted in response to the changed environment.
This adaptation of the poppies to their new environment is due to directional selection. The characteristics of the poppies shifted in response to the changed environment.
What is directional selection?
In population genetics, directed selection is a mode of negative natural selection in which one extreme phenotype is favored over the other, causing allele frequencies to shift towards that phenotype over time. . Under directional selection, favorable alleles increase as a result of survival and reproductive differences between different phenotypes. The increase is independent of allele dominance and is eventually fixed even if the allele is recessive. First described as a form of natural selection. Other types of natural selection include stabilizing selection and perturbing selection. Each type of selection involves the same principles, but is slightly different. Destructive selection favors both extreme phenotypes distinct from extreme directional selection. Stabilizing selection favors an intermediate phenotype and reduces population variation over time.
Therefore, This adaptation of the poppies to their new environment is due to directional selection.

The median estimated body-mass index is highly correlated with conventional measure of corruption. This result suggest that physical characteristics of politicians such as their body-mass index can be used as a variable for political corruption.
From graph 2, "increased body in government ministers may indicates higher corruption".
The most corrupt countries tend to have the most overweight polliticians. The countries conventionally rated least corrupt in the post-Soviet world are Estonia, Latvia, Lithuania, and Georgia.
There might be a health benefit to political corruption- Higher obesity rates among top politicians but lower obesity rates in the general population. Relatively less corrupt countries have slimmer politicians but more overweight voters.

Jaguars are important predators of adult sea turtles when they come to lay their eggs and of the eggs themselves. Which of the below statements is true regarding this system?All of these
Jaguars are top predators which are always uncommon
Because of inefficiency in energy transfer between trophic levels, there is not enough food to support very dense jaguar populations in most habitats
Jaguars usually need to roam large distances in order to obtain enough food
The Tortuguero jaguar population is being supported in part by trophic levels in the ocean, rather than just on land
Jaguars typically have to travel great distances to find enough food.
Rather than merely on land, trophic levels in the ocean help to feed the Tortuguero jaguar population. In most ecosystems, food is insufficient to support particularly dense jaguar populations due to inefficiencies in energy transfer across trophic levels. In contrast to cheetahs and lions, which chase their prey throughout the night, jaguars stalk and ambush their ground-dwelling prey. Although they are capable of running fairly swiftly, Jaguars do not need this ability. They can kill their prey by penetrating the skull with their sharp teeth thanks to their strong jaw muscles.

Wheat is attacked by many different pests, including a fungus called yellow rust.
a Describe how you could use artificial selection to produce a new variety of wheat which is naturally resistant to yellow rust.
When resistant varieties of wheat are produced, it is found that after a few years they are infected by yellow rust again. Explain how this might happen
Answer:Puccinia striiformis f.
Stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a serious disease of wheat occurring in most wheat areas with cool and moist weather conditions during the growing season. The basidiomycete fungus is an obligate biotrophic parasite that is difficult to culture on artificial media.
Explanation:Does rust turn black?

Rust from Iron (III) oxides with limited oxygen and low moisture results in black rust. Black rust can be visually identified as a thin, black film which is the result of oxidation in a low oxygen environment.
There are several fungicides that can be used to protect plants from infection. Mancozeb as a protectant and myclobutanil as an eradicant are generally effective against all rusts while triadimefon is effective against only specific rusts.
