Answer:
No
Explanation:
because genetic drift is random
The <u>environment</u> is what we live in. <u>Dependence</u> is the act of living alone. <u>Consumer</u> is what we are. <u>Predators</u> are very skilled hunters. <u>Competition</u> is the act of competing. <u>Extinct</u> is what the dinosaurs are. <u>Decomposers</u> are fungi earthworms. <u>Recycle</u> is one of the three R's they are Reuse Reduce and Recycle. <u>Endangered</u> is a very very small or things that are no more. <u>Producers</u> are plants. <u>Food Chain</u> is a figurative "chain". <u>Sun light</u> is what helps plants grow. <u>Nutrients</u> is what helps us grow and survive <u>Species</u> are a group of animals <u>Biotic</u> is living like us. <u>Prey</u> is what the <u>predators</u> eat <u>Adaptation</u> is the change of different things <u>Energy</u> is what is released and <u>Abiotic</u> is nonliving.
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.
The structure of the ear that conducts sound waves to the middle ear is the oval window.
Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.
Human impact on the environment can manifest as:
- overpopulation- natural resources are over used, and habitats cannot support human communities;
- urban communities also expand by cutting down trees in deforestation- this leads to erosion and flooding;
- burning fossil fuels- this reduces air quality and adds carbon dioxide to the environment leading to global warming;
- pollution- adding contaminants to the atmosphere, waterways, soil etc.
Leaves change in the fall via a natural process; in green leaves the photosynthetic pigment, Chlorphyll a is produced in significantly lower amounts. Other pigment molecules that absorb and reflect different wavelengths exist in larger concentrations- their effect is more apparent, leading to visibly orange-red leaves.
