where is this ecoregion located?

Answer:

1. Animals may to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather some animals will hibernate. Examples of hibernating animals maybe ants, snakes, black bears, beavers, and ground squirrels.

2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.

Explanation:

Answer:

a) For example, a cat may see a saucer of milk. Information from

the cat’s eyes travels along nerve cells to the brain, where the brain

processes the information. If the brain decides it wants the milk,

the brain sends a signal to the muscles in the cat’s limbs, and the cat

moves to the saucer of milk and drinks it

Explanation:

b)  For example,

specialized cells in the leaves of trees detect the decrease in sunlight

as winter approaches. Chloroplasts then reduce production of green

chlorophyll. As existing chlorophyll is broken down, other coloured

particles are revealed, creating the beautiful red- and orange-coloured

leaves we see during autumn. Th e leaves eventually die and fall off . In

the spring, increased sunlight and warmer temperatures promote the

production of new leaves containing large amounts of chlorophyll, and

the green colour returns to the leaves.

deer are not carnivores

a carnivore is an animal that only eats meat, and some of these animals also eat plants (like baby frogs/tadpoles, which are herbivores)

c increases genetic diversity

Explanation:

Answer:

C. increases genetic diversity

Explanation:

First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

hope this helps:)

Answer:

Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.

Surface currents are created by three things:

global wind patterns

the rotation of the Earth

the shape of the ocean basins

Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.

Answer:

The Coriolis effect causes winds and currents to form circular patterns.

Answer:

ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

Answer:

Genetically modified crops (GM crops) are those engineered to introduce a new trait into the species. Purposes of GM crops generally include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide).

Answer: B

the traits for white fur and red eyes were always inherited together.

Explanation:

The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.

So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Answer:

sickle cell anemia and malaria

Explanation:

Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.

The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.

The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.

The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Horses belong to a group of mammals with an odd number of toes. That rules out mammals with two toes, or "cloven hooves," like goats, pigs, cows, deer, and camels. So who are the other odd-toed, plant-eating animals? Most members of this group, known as perissodactyls, are extinct.
