Eggs were found to evolve for over a billion years ago whereas chicken have been found to evolve around for just over 10,000 years. Thus, it can be concluded that eggs came first followed by the chicken.
What is Evolution?Evolution can be defined as any net directional change or cumulative change in the characteristics or traits of an organism or populations over many generations in order to survive better in the surrounding environment.
Eggs come from chickens and chickens come from eggs. It is the ancient riddle. However, eggs are just the female sex cells which were supposed to have evolved more than a billion years ago, whereas chickens have been found to evolve around for just 10,000 years ago. Therefore, it can be said that the eggs have came first followed by chickens.
The amniotic eggs shows up to roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest. Thus, eggs were around way before chickens even existed.

pako sagot plss
Answer:
3) CO2 + water
4) producers
5) oxygen
Explanation:
Autotrophs are producers which use sunlight, water and carbon dioxide to make their own food. This occurs via the process of photosynthesis in green plants, algae ,phytoplankton and cyanobacteria. These occupy essential places in the food web, and provide the energy used by hetertrophs or consumers.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Consumers carry out respiration to obtain the energy stored in carbohydrates produced by plants.
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land
plzzz helpp
I meant years not tears
Answer:
so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase
Explanation:
what I just said lol
Answer:
Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

Consciousness can best be described as __(blank)__.
a) Internal chemical systems that are regulated by a circadian rhythm
b) an ability to sleep and have lucid dreams
c) a lack of awareness of things going on inside or outside of yourself
d) an awareness of things going on inside or outside of yourself
Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.
How consciousness is regulated?Wakefulness/arousal and awareness are frequently used as the two components that make up consciousness.
It appears that proper arousal levels and subsequently wakefulness, which is required for consciousness, depend on well-synchronized phases of awake and sleep.
Circadian rhythms are changes in the body, brain, and behavior that occur on a 24-hour cycle. Most living things, including animals, plants, and bacteria, are impacted by these natural processes, which predominantly react to light and darkness.
Therefore, the 24-hour cycle of normal physical, emotional, and behavioral changes that the body experiences.

Running for a long period of time, such as during a marathon, can result in muscle fatigue. Which process is important to a runner at the end of a marathon?
A. lactic acid fermentation to produce ATP without oxygen
B. Alchoholic fermentation to release carbon dioxide
C. The Krebs cycle to produce NADH and FADH2
D. The electron transport chain to produce ATP
The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?
When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.
