Why is blue green algae considered a connecting link between lower and higher animals?
As blue green algae are not animals, they do not represent an evolutionary link between any forms of animals. However, I'm not sure that I'm understanding your question. B Blue-green algae are Monera, neither plants nor animals nor algae. They share the characteristic with bacteria of not having a nucleus

What basic difference exists between the life cycle of higher plants and higher animals?
I got this from someone off of yahoo. I think the answer has something to do with how the gametes are formed. In animals, the gametes are formed from through spermatogenesis in males and oogenesis in females. The process the cells undergo is meiosis. In plants however, the formation of gametes have a few more steps. The spore phase, gametophyte phase and finally gametes. So the basic differences that exists between the life cycles of higher plants and higher animals is how the gametes are formed. Higher animals have "one" basic step to forming gametes while higher plants have several.
What are the differences between prehistoric and modern animals respiratory system?
Prehistoric animals likely had simpler respiratory systems compared to modern animals, with less efficient mechanisms for obtaining and circulating oxygen. Modern animals have evolved more complex respiratory structures, such as lung adaptations and specialized gas exchange systems, to meet the higher oxygen demands of their metabolisms. Additionally, modern animals have a wider diversity of respiratory adaptations to different environments compared to prehistoric animals.
Do all animals hear the same frequencies of sound as human do?
Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
What type of organism reproduce sexually?
Mostly higher plants and animals.
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
What is the difference between connecting wire and heating element?
The connecting wire will be thicker and made of a low resistance material to allow electricity to flow with minimal losses. The element requires a thinner wire with higher resistivity which causes it to heat when electricity passes through.
What is the motto of UCAS?
UCAS's motto is 'At the heart of connecting people to higher education'.
What defines an overweight person?
For adults, you are considered overweight if your BMI (body mass index) is between 25 and 29.9. If your BMI is 30 or higher, you are considered obese.
Why are humans considered more important than animals?
Humans are considered more important than animals because of our higher level of intelligence, ability to create complex societies, and capacity for self-awareness and moral reasoning. These qualities give us the ability to make decisions, solve problems, and shape the world in ways that animals cannot.
What is the main difference between humans and animals?
The main difference between humans and animals is that humans have a higher level of cognitive abilities, including complex language, reasoning, and self-awareness, which allow us to create advanced civilizations and technologies.
Why are some pollutants more harmful to organisms at higher trophic levels?
Higher trophic levels are animals that are higher up on the food chain. When animals lower on the food chain get effected by pollutants, it transfers to the animal that eats that one. And so on. So the animals on the higher trophic level eat the most animals(animals with the pollutants).

Why are human lives considered more important than animals?
Human lives are considered more important than animals due to the belief that humans possess higher cognitive abilities, complex emotions, and the capacity for moral reasoning. Additionally, many societies prioritize human well-being and advancement over that of animals based on cultural, ethical, and religious beliefs.
Why do smaller animals have a higher metabolism compared to larger animals?
Smaller animals have a higher metabolism compared to larger animals because they have a higher surface area-to-volume ratio, which means they lose heat more quickly and need to generate more energy to maintain their body temperature.
What are the minimum requirements for ACT at Duke University?
Anywhere between 35 or 36 or higher is considered decent at Duke
How do higher forms of animals reproduces?
asexually
Why do small animals have higher metabolic rates compared to larger animals?
Small animals have higher metabolic rates compared to larger animals because they have a higher surface area-to-volume ratio, which means they lose heat more quickly and need to generate more energy to maintain their body temperature.
